Abstract
Yeast strains are convenient models for studying domestication processes. The ability of yeast to ferment carbon sources from various substrates and to produce ethanol and carbon dioxide is the core of brewing, winemaking, and ethanol production technologies. The present study reveals the differences among yeast strains used in various industries. To understand this, we performed a proteomic study of industrial Saccharomyces cerevisiae strains followed by a comparative analysis of available yeast genetic data. Individual protein expression levels in domesticated strains from different industries indicated modulation resulting from response to technological environments. The innovative nature of this research was the discovery of genes overexpressed in yeast strains adapted to brewing, baking, and ethanol production, typical genes for specific domestication were found. We discovered a gene set typical for brewer's yeast strains. Baker's yeast had a specific gene adapted to osmotic stress. Toxic stress was typical for yeast used for ethanol production. The data obtained can be applied for targeted improvement of industrial strains.

Abstract
Hypoxanthine-guanine phosphoribosyltransferase (HGPRT) is a key enzyme of the purine recycling pathway that catalyzes the conversion of 5-phospho-ribosyl-α-1-pyrophosphate and guanine or hypoxanthine to guanosine monophosphate (GMP) or inosine monophosphate (IMP), respectively, and pyrophosphate (PPi). We report the first crystal structure of a fungal 6-oxopurine phosphoribosyltransferase, the Saccharomyces cerevisiae HGPRT (Sc-HGPRT) in complex with GMP. The crystal structures of full length protein with (WT1) or without (WT2) sulfate that mimics the phosphate group in the PPi binding site were solved by molecular replacement using the structure of a truncated version (Δ7) solved beforehand by multiwavelength anomalous diffusion. Sc-HGPRT is a dimer and adopts the overall structure of class I phosphoribosyltransferases (PRTs) with a smaller hood domain and a short two-stranded parallel β-sheet linking the N- to the C-terminal end. The catalytic loops in WT1 and WT2 are in an open form while in Δ7, due to an inter-subunit disulfide bridge, the catalytic loop is in either an open or closed form. The closure is concomitant with a peptide plane flipping in the PPi binding loop. Moreover, owing the flexibility of a GGGG motif conserved in fungi, all the peptide bonds of the phosphate binding loop are in trans conformation whereas in nonfungal 6-oxopurine PRTs, one cis-peptide bond is required for phosphate binding. Mutations affecting the enzyme activity or the previously characterized feedback inhibition by GMP are located at the nucleotide binding site and the dimer interface.

Abstract
Hypoxanthine-guanine phosphoribosyltransferase (HGPT) occurs in both eukaryotic and prokaryotic organisms. However, the molecular and functional properties of plant HGPT are not well understood. In this study, it was found that the putative HGPT proteins from dicot and monocot plant species exhibited significant identities to their homologs from other cellular organisms. Ectopic expression of the HGPTs from Arabidopsis, soybean or wheat complemented HGPT deficiency in the hpt1 mutant of Saccharomyces cerevisiae. Recombinant Arabidopsis HGPT (AtHGPT) catalyzed both forward and reverse reactions in in vitro biochemical assays. The relative catalytic efficiency for the synthesis of guanosine monophosphate (GMP) was significantly greater than that for the production of guanine from GMP. Further investigations led to identification of the candidate residues that may form the pyrophosphate (PPi) binding loop in AtHGPT. AtHGPT expression level was dynamically regulated in Arabidopsis organs and during leaf development and senescence and seed germination. AtHGPT knockout mutant germinated more slowly than wild type control, whereas its overexpression mutant exhibited accelerated germination. Collectively, the data suggest that functional HGPTs are expressed in higher plants. In Arabidopsis, HGPT plays an active role in the salvage of purine bases and its activity is required for efficient seed germination.

Abstract
Phosphoribosyltransferase (PRTase) and nucleoside phosphorylase (NPase) activities were detected by radiometric methods in extracts of Methanococcus voltae. Guanine PRTase activity was present at 2.7 nmol min(-1) mg of protein(-1) and had an apparent Km for guanine of 0.2 mM and a pH optimum of 9. The activity was inhibited 50% by 0.3 mM GMP. IMP and AMP were not inhibitory at concentrations up to 0.6 mM. Hypoxanthine inhibited by 50% at 0.16 mM, and adenine and xanthine were not inhibitory at concentrations up to 0.5 mM. Guanosine NPase activity was present at 0.01 nmol min(-1) mg of protein(-1). Hypoxanthine PRTase activity was present at 0.85 nmol min(-1) mg of protein(-1) with an apparent Km for hypoxanthine of 0.015 mM and a pH optimum of 9. Activity was stimulated at least twofold by 0.05 mM GMP and 0.2 mM IMP but was unaffected by AMP. Guanine inhibited by 50% at 0.06 mM, but adenine and xanthine were not inhibitory. Inosine NPase activity was present at 0.04 nmol min(-1) mg of protein(-1). PRTase activities were not sensitive to any base analogs examined, with the exception of 8-azaguanine, 8-azahypoxanthine, and 2-thioxanthine. Fractionation of cell extracts by ion-exchange chromatography resolved three peaks of activity, each of which contained both guanine and hypoxanthine PRTase activities. The specific activities of the PRTases were not affected by growth in medium containing the nucleobases. Mutants of M. voltae resistant to base analogs lacked PRTase activity. Two mutants resistant to both 8-azaguanine and 8-azahypoxanthine lacked activity for both guanine and hypoxanthine PRTase. These results suggest that analog resistance was acquired by the loss of PRTase activity.

Abstract
Adenine phosphoribosyltransferase (APRTase) and hypoxanthine-guanine phosphoribosyltransferase (HGPRTase) have been purified from Artemia cysts and nauplii to apparent homogeneity, as determined by SDS-PAGE. The purification includes affinity chromatography on AMP-Sepharose, which binds both enzymes, and they are eluted at different 5-phospho-alpha-D-ribosyl diphosphate (PP-Rib-P) concentrations. The purified enzymes from Artemia cysts were similar to nauplii enzymes with respect to Mr in denaturing gel electrophoresis and gel filtration, pH and cation dependence and kinetic constants for substrates and inhibitors. By Sephadex G-100 filtration, the native Mr of the adenine and hypoxanthine-guanine enzymes was estimated to be Mr 28,000 and 66,000, respectively. Analysis by SDS-PAGE revealed that the APRTase was a dimer of Mr 15,000 sub-units and the HGPRTase, a tetramer of four identical Mr 19,000 sub-units. The pH profile of the HGPRTase shows two apparent buffer-independent pH optima, at 7.0 and 9.5, while the APRTase has just one, at about pH 8-9. The purine phosphoribosyltransferase activity with adenine was highest, about tenfold the HGPRTase activity with hypoxanthine and fivefold that with guanine. Both enzymes exhibited similar requirements for divalent cations, either Mg2+, Mn2+ or Zn2+, while Ca2+ is highly inhibitory. The Km values of APRTase for adenine and PP-Rib-P are 2 and 30 microM, respectively, and the Km values of HGPRTase for hypoxanthine, guanine and PP-Rib-P are less than 1, less than 1 and 15 microM, respectively. Plots of the reciprocal enzyme activities versus reciprocal concentrations of one substrate at several fixed levels of the second one yield a pattern of inhibition by guanine and hypoxanthine. Product-inhibition studies indicated that AMP is a competitive inhibitor with respect to PP-Rib-P in the APRTase reaction, while the HGPRTase shows a mixed inhibition by GMP.

Abstract
Hypoxanthine-guanine phosphoribosyltransferase (HPRT) catalyzes the conversion of hypoxanthine and guanine to IMP and GMP, respectively, in the presence of 5-phosphoribosyl-1-pyrophosphate. Deficiencies of HPRT are associated with neurological abnormalities and gout. A human HPRT variant enzyme failed to bind to a GMP-affinity column under standard purification conditions. We developed a series of predictive tests for designing the affinity chromatography protocol which enabled purification of both normal and variant HPRT. The primary variable for the present variant was a difference in toleration of salt; other aspects recommended for evaluation are assessment of ligand-enzyme affinity, pH optimum, and tolerance of nonspecific ligands for washes. In addition, a method for determining the amount of GMP linked to the column material was developed and consisted of acid hydrolysis and HPLC quantitation of guanine.

Abstract
Spontaneous and ethyl methanesulfate induced mutants of Saccharomyces cerevisiae, with partial and complete deficiency of adenine phosphoribosyltransferase (APRT, EC 2.4.2.7), were isolated by selection for resistance to 8-azaadenine. Matings between totally deficient mutants and tester strain resulted in diploid heterozygotes that were sensitive to azaadenine. Upon sporulation and tetrad analysis, azaadenine resistance (and APRT deficiency) segregated as expected for a single Mendelian gene. Hypoxanthine-guanine phosphoribosyltransferase (EC 2.4.2.8) activity in the mutants was similar to that in the wild-type cells. There was no detectable activity of adenine aminohydrolase (EC 3.5.4.2) in the wild-type or mutant cells.

Abstract
A rapid and simple method, based on GMP Sepharose affinity chromatography, was used for the purification of human brain hypoxanthine guanine phosphoribosyltransferase. A single protein band was detected by polyacrylamide gel electrophoresis of the native purified enzyme. A subunit molecular weight of 25,000 was estimated by SDS gel electrophoresis. The Km values for hypoxanthine and phosphoribosyl pyrophosphate were 50 and 111 microM, respectively. The Ki values for GMP and IMP with phosphoribosyl pyrophosphate were 21 and 37 microM, respectively. The purified enzyme from human brain did not differ significantly from the human erythrocyte one in amino acid composition. The brain and erythrocyte hypoxanthine guanine phosphoribosyltransferases showed complete immunochemical identity on Ouchterlony double diffusion.

Abstract
A facile and rapid purification procedure, based upon the heat denaturation of extraneous proteins and GMP-Sepharose affinity chromatography, has been used to purify hypoxanthine phosphoribosyltransferase from human brain. A homogeneous enzyme preparation, as judged by sodium dodecyl sulfate and gradient polyacrylamide gel electrophoresis, was obtained. The subunit molecular weight of the enzyme was estimated as 24,000 by sodium dodecyl sulfate polyacrylamide gel electrophoresis. The native molecular weight, determined by gradient gel electrophoresis, was approximately 100,000. These results suggest human brain hypoxanthine phosphoribosyltransferase is a tetramer, consistent with recent results reported for the human erythrocyte enzyme. At least three charge variant forms of the human brain enzyme were distinguished by nondenaturing polyacrylamide gel electrophoresis, electrofocusing, and chromatofocusing. Acidic pI values of approximately 5.7, 5.5, and 5.0 were estimated for the three major species.

Abstract
Yeast mutants lacking activity of the enzyme hypoxanthine:guanine phosphoribosyltransferase (H:G-PRT) have been isolated by selecting for resistance to 8-azaguanine in a strain carrying the wild type allele, ade4%, of the gene coding for amidophosphoribosyltransferase (PRPPAT), the first enzyme of de novo purine synthesis. The mutants excrete purines and are cross-resistant to 8-azaadenine. They are recessive and represent a single complementation group, designated hpt1. Ade4-su, a prototrophic allele of ade4 with reduced activity of PRPPAT, is epistatic to hpt1, suppressing purine excretion and resistance to azaadenine but not resistance to azaguanine. The genotype ade2hpt1 does not respond to hypoxanthine. Hpt1 complements and is not closely linked to the purine excreting mutants pur1 to pur5. Hpt1 and pur6, a regultory mutant of PRPPAT, are also unlinked but do not complement, suggesting a protein-protein interaction between H:G-PRT and PRPPAT. Mycophenolic acid (MPA), an inhibitor of de novo guanine nucleotide synthesis, inhibits the growth of hpt1 and hpt1+. Xanthine allows both genotypes to grow in the presence of MPA whereas guanine only allows growth of hpt1+. Activity of A-PRT, X-PRT and H:G-PRT is present in hpt+. Hpt1 lacks activity of H:G-PRT but has normal A-PRT and X-PRT.
