Abstract
Opines and opine-type chemicals are valuable natural products with diverse biochemical roles, and potential synthetic building blocks of bioactive compounds. Their synthesis involves reductive amination of ketoacids with amino acids. This transformation has high synthetic potential in producing enantiopure secondary amines. Nature has evolved opine dehydrogenases for this chemistry. To date, only one enzyme has been used as biocatalyst, however, analysis of the available sequence space suggests more enzymes to be exploited in synthetic organic chemistry. This review summarizes the current knowledge of this underexplored enzyme class, highlights key molecular, structural, and catalytic features with the aim to provide a comprehensive general description of opine dehydrogenases, thereby supporting future enzyme discovery and protein engineering studies.

Abstract
Novel imine reductase from yeast Candida parapsilosis purified and characterized. CpIM1 belongs to unexplored Ornithine cyclodeaminase/Mu crystallin protein family CpIM1 catalyzed stereospecific alkylamination of α-ketoacids/ketoesters. CpIM1 also reduced cyclic and aryl imines. First report on enzymatic alkylamination of α-ketoesters and reduction of arylimines.
We report a stereospecific imine reductase from Candida parapsilosis ATCC 7330 (CpIM1), a versatile biocatalyst and a rich source of highly stereospecific oxidoreductases. The recombinant gene was overexpressed in Escherichia coli and the protein CpIM1 was purified to homogeneity. This protein belongs to the Ornithine cyclodeaminase/ μ-crystallin (OCD-Mu) family of proteins which has only a few characterized members. CpIM1 catalyzed the alkylamination of α-keto acids/esters producing exclusively (S)-N-alkyl amino acids/esters e.g. N-methyl-l-alanine with > 90% conversion and > 99% enantiomeric excess (ee). The enzyme showed the highest activity for the alkylamination of pyruvate and methylamine leading to N-methyl-l-alanine with an apparent KM of 15.04 ± 2.8 mM and Vmax of 13.75 ± 1.07 μmol/min/mg. CpIM1 also catalyzed (i) the reduction of imines e.g. 2-methyl-1-pyrroline to (S)-2-methylpyrrolidine with ∼30% conversion and 75% ee and (ii) the dehydrogenation of cyclic amino acids e.g. l-Proline (as monitered by reduction of cofactor NADP+ spectrophotometrically).

Abstract
Ornithine cyclodeaminase homolog from an archeon was characterized biochemically. This protein functions as a novel Δ1-pyrroline-2-carboxylate reductase. This enzyme is probably involved in trans-3-hydroxy-l-proline metabolism as in bacteria and mammals.
l-Ornithine cyclodeaminase (OCD) is involved in l-proline biosynthesis and catalyzes the unique deaminating cyclization of l-ornithine to l-proline via a Δ1-pyrroline-2-carboxyrate (Pyr2C) intermediate. Although this pathway functions in only a few bacteria, many archaea possess OCD-like genes (proteins), among which only AF1665 protein (gene) from Archaeoglobus fulgidus has been characterized as an NAD+-dependent l-alanine dehydrogenase (AfAlaDH). However, the physiological role of OCD-like proteins from archaea has been unclear. Recently, we revealed that Pyr2C reductase, involved in trans-3-hydroxy-l-proline (T3LHyp) metabolism of bacteria, belongs to the OCD protein superfamily and catalyzes only the reduction of Pyr2C to l-proline (no OCD activity) [FEBS Open Bio (2014) 4, 240–250]. In this study, based on bioinformatics analysis, we assumed that the OCD-like gene from Thermococcus litoralis DSM 5473 is related to T3LHyp and/or proline metabolism (TlLhpI). Interestingly, TlLhpI showed three different enzymatic activities: AlaDH; N-methyl-l-alanine dehydrogenase; Pyr2C reductase. Kinetic analysis suggested strongly that Pyr2C is the preferred substrate. In spite of their similar activity, TlLhpI had a poor phylogenetic relationship to the bacterial and mammalian reductases for Pyr2C and formed a close but distinct subfamily to AfAlaDH, indicating convergent evolution. Introduction of several specific amino acid residues for OCD and/or AfAlaDH by site-directed mutagenesis had marked effects on both AlaDH and Pyr2C reductase activities. The OCC_00387 gene, clustered with the TlLhpI gene on the genome, encoded T3LHyp dehydratase, homologous to the bacterial and mammalian enzymes. To our knowledge, this is the first report of T3LHyp metabolism from archaea.

Abstract
Three cDNA sequences encoding putative opine dehydrogenase (OpDH) enzymes from the mussel Mytilus galloprovincialis were obtained. The deduced amino acid sequences were clearly distinguishable from each other, showing that several OpDH transcripts could occur in the mussel tissues (p distance 0.46-0.55). When these sequences were aligned and compared with published databank proteins, the range of identity among the M. galloprovincialis OpDH and the strombine dehydrogenase from Ostrea edulis was 51-59 %, the best hit in the three comparisons, followed by OpDH enzymes from other marine invertebrates. Sequence alignment revealed structural motifs possibly related to the binding sites of the substrates. A phylogenetic analysis compared M. galloprovincialis OpDH and annotated sequences belonging to five phyla and seven taxonomic classes, including 19 species, representing the five OpDH protein family members. The phylogenetic tree clustered the OpDH enzymes according to the evolutionary relationships of the species and not to the biochemical reaction catalyzed.

Abstract
Major insights into the phylogenetic distribution, biochemistry, and evolutionary significance of organelles involved in ATP synthesis (energy metabolism) in eukaryotes that thrive in anaerobic environments for all or part of their life cycles have accrued in recent years. All known eukaryotic groups possess an organelle of mitochondrial origin, mapping the origin of mitochondria to the eukaryotic common ancestor, and genome sequence data are rapidly accumulating for eukaryotes that possess anaerobic mitochondria, hydrogenosomes, or mitosomes. Here we review the available biochemical data on the enzymes and pathways that eukaryotes use in anaerobic energy metabolism and summarize the metabolic end products that they generate in their anaerobic habitats, focusing on the biochemical roles that their mitochondria play in anaerobic ATP synthesis. We present metabolic maps of compartmentalized energy metabolism for 16 well-studied species. There are currently no enzymes of core anaerobic energy metabolism that are specific to any of the six eukaryotic supergroup lineages; genes present in one supergroup are also found in at least one other supergroup. The gene distribution across lineages thus reflects the presence of anaerobic energy metabolism in the eukaryote common ancestor and differential loss during the specialization of some lineages to oxic niches, just as oxphos capabilities have been differentially lost in specialization to anoxic niches and the parasitic life-style. Some facultative anaerobes have retained both aerobic and anaerobic pathways. Diversified eukaryotic lineages have retained the same enzymes of anaerobic ATP synthesis, in line with geochemical data indicating low environmental oxygen levels while eukaryotes arose and diversified.

Abstract
Strombine dehydrogenase (SDH, EC 1.5.1.22) from the foot of the hard clam Meretrix lusoria was purified over 470-fold to apparent homogeneity. It has a monomeric structure with a relative molecular mass of 46,000. Two isoenzymes were identified with isoelectric points of 6.83 and 6.88. SDH is heat labile, and has pH and temperature optima of 7.4-7.6 and 45-46°C, respectively. l-Alanine, glycine, and pyruvate are the preferred substrates. l-Serine is the third preferred amino acid. Iminodiacetate with the lowest K(i) of SDH at both pH 6.5 and 7.5 was the strongest inhibitor among succinate, acetate, iminodiacetate, oxaloacetate, and l-/d-lactate. The inhibitory activities of succinate at pH 6.5, and iminodiacetate and oxaloacetate at pH 7.5 on the SDH were higher. These inhibitors are either competitive or mixed-competitive inhibitors. Half of the enzymatic activity of SDH was inhibited by 0.2mM Fe(3+) and 0.6mM Zn(2+).
