Abstract
Animal pigment patterns play important roles in behavior and, in many species, red coloration serves as an honest signal of individual quality in mate choice. Among Danio fishes, some species develop erythrophores, pigment cells that contain red ketocarotenoids, whereas other species, like zebrafish (D. rerio) only have yellow xanthophores. Here, we use pearl danio (D. albolineatus) to assess the developmental origin of erythrophores and their mechanisms of differentiation. We show that erythrophores in the fin of D. albolineatus share a common progenitor with xanthophores and maintain plasticity in cell fate even after differentiation. We further identify the predominant ketocarotenoids that confer red coloration to erythrophores and use reverse genetics to pinpoint genes required for the differentiation and maintenance of these cells. Our analyses are a first step toward defining the mechanisms underlying the development of erythrophore-mediated red coloration in Danio and reveal striking parallels with the mechanism of red coloration in birds.

Immunoaffinity purification and characterization of mitochondrial membrane-bound D-3-hydroxybutyrate dehydrogenase from Jaculus orientalis. BMC BIOCHEMISTRY 2008; 9:26.

Abstract
BACKGROUND The interconversion of two important energy metabolites, 3-hydroxybutyrate and acetoacetate (the major ketone bodies), is catalyzed by D-3-hydroxybutyrate dehydrogenase (BDH1: EC 1.1.1.30), a NAD+-dependent enzyme. The eukaryotic enzyme is bound to the mitochondrial inner membrane and harbors a unique lecithin-dependent activity. Here, we report an advanced purification method of the mammalian BDH applied to the liver enzyme from jerboa (Jaculus orientalis), a hibernating rodent adapted to extreme diet and environmental conditions. RESULTS Purifying BDH from jerboa liver overcomes its low specific activity in mitochondria for further biochemical characterization of the enzyme. This new procedure is based on the use of polyclonal antibodies raised against BDH from bacterial Pseudomonas aeruginosa. This study improves the procedure for purification of both soluble microbial and mammalian membrane-bound BDH. Even though the Jaculus orientalis genome has not yet been sequenced, for the first time a D-3-hydroxybutyrate dehydrogenase cDNA from jerboa was cloned and sequenced. CONCLUSION This study applies immunoaffinity chromatography to purify BDH, the membrane-bound and lipid-dependent enzyme, as a 31 kDa single polypeptide chain. In addition, bacterial BDH isolation was achieved in a two-step purification procedure, improving the knowledge of an enzyme involved in the lipid metabolism of a unique hibernating mammal. Sequence alignment revealed conserved putative amino acids for possible NAD+ interaction.

Abstract
(R)-3-Hydroxybutyrate dehydrogenase (BDH) is a lipid-requiring mitochondrial enzyme that has a specific requirement of phosphatidylcholine (PC) for function. The C-terminal domain (CTBDH) of human heart BDH (residues 195-297) has now been expressed in Escherichia coli as a chimera with a soluble protein, glutathione S-transferase (GST), yielding GST-CTBDH, a novel fusion protein that has been purified and shown to selectively bind to PC vesicles. Both recombinant human heart BDH (HH-Histag-BDH) and GST-CTBDH (but not GST) form well-defined protein-lipid complexes with either PC or phosphatidylethanolamine (PE)/diphosphatidylglycerol (DPG) vesicles (but not with digalactosyl diglyceride vesicles) as demonstrated by flotation in sucrose gradients. The protein-PC complexes are stable to 0.5 M NaCl, but complexes of either HH-Histag-BDH or GST-CTBDH with PE/DPG vesicles are dissociated by salt treatment. Thrombin cleavage of GST-CTBDH, either before or after reconstitution with PC vesicles, yields CTBDH (12 111 Da by MALDI mass spectrometry) which retains lipid binding without attached GST. The BDH activator, 1-palmitoyl-2-(1-pyrenyl)decanoyl-PC (pyrenyl-PC), at <2.5% of total phospholipid in vesicles, efficiently quenches a fraction (0.36 and 0.47, respectively) of the tryptophan fluorescence of both HH-Histag-BDH and GST-CTBDH with effective Stern-Volmer quenching constants, (K(Q))(eff), of 11 and 9.3 (%)(-)(1), respectively (half-maximal quenching at approximately 0.1% pyrenyl-PC). Maximal quenching by pyrenyl-PC obtains at approximately stoichiometric pyrenyl-PC to protein ratios, reflecting high-affinity interaction of pyrenyl-PC with both HH-Histag-BDH and GST-CTBDH. The analogous pyrenyl-PE effects a similar maximal quenching of tryptophan fluorescence for both proteins but with approximately 15-fold lower (K(Q))(eff) (half-maximal quenching at approximately 1.5% pyrenyl-PE) referable to nonspecific interaction of pyrenyl-PE with HH-Histag-BDH or GST-CTBDH. Thus, the 103-residue CTBDH constitutes a PC-selective lipid binding domain of the PC-requiring BDH.

Abstract
We have cloned and sequenced the 3-hydroxybutyrate dehydrogenase-encoding gene (bdhA) from Rhizobium (Sinorhizobium) meliloti. The gene has an open reading frame of 777 bp that encodes a polypeptide of 258 amino acid residues (molecular weight 27,177, pI 6.07). The R. meliloti Bdh protein exhibits features common to members of the short-chain alcohol dehydrogenase superfamily. bdhA is the first gene transcribed in an operon that also includes xdhA, encoding xanthine oxidase/dehydrogenase. Transcriptional start site analysis by primer extension identified two transcription starts. S1, a minor start site, was located 46 to 47 nucleotides upstream of the predicted ATG start codon, while S2, the major start site, was mapped 148 nucleotides from the start codon. Analysis of the sequence immediately upstream of either S1 or S2 failed to reveal the presence of any known consensus promoter sequences. Although a sigma54 consensus sequence was identified in the region between S1 and S2, a corresponding transcript was not detected, and a rpoN mutant of R. meliloti was able to utilize 3-hydroxybutyrate as a sole carbon source. The R. meliloti bdhA gene is able to confer upon Escherichia coli the ability to utilize 3-hydroxybutyrate as a sole carbon source. An R. meliloti bdhA mutant accumulates poly-3-hydroxybutyrate to the same extent as the wild type and shows no symbiotic defects. Studies with a strain carrying a lacZ transcriptional fusion to bdhA demonstrated that gene expression is growth phase associated.
