BchC preferentially oxidizes 31R-3-(1-hydroxyethyl)-chlorophyllide a and 31R-3-(1-hydroxyethyl)-bacteriochlorophyllide a in the presence of NAD+ to 3-acetylchlorophyllide a and bacteriochlorophyllide a, respectively, leaving the unreacted 31S-epimers. In the reverse reaction, BchC with NADH predominately produces 31R-epimeric alcohols from the 3-acetyl-(bacterio)chlorins. 31R-selectivity, overview. While most naturally occurring (B)Chls including BChl a have a magnesium ion at the center of the cyclic tetrapyrrole ring, zinc-chelated BChl a has been found in some organisms. BchC exhibits oxidation activity on zinc 3-(1-hydroxyethyl)-pheophorbide (Zn-3HE-Pheide) a, albeit at a low level, where the R-epimer is consumed as a substrate to a greater extent than is the S-epimer. The reduction of Zn-3Ac-Pheide a by BchC in the presence of NADH is also observed, predominantly producing the R-epimer of Zn-3HE-Pheide a. The chlorin pigments lacking a central metal, 3HE-Pheide a and 3Ac-Pheide a, are not suitable for substrates of BchC in the presence of NAD+ or NADH, respectively. Thus, the central metal atoms, Mg and Zn, in the substrates are necessary for BchC-catalyzed reaction. Determination of the 31-stereochemistry of 3HEChlide a and 3HE-BChlide a, overview

BchC oxidoreductase is involved in bacteriochlorophyll a biosynthesis. The presence of BchC accelerates the 3-vinyl hydration by BchF hydratase of Chlorobaculum tepidum during conversion of chlorophyllide a to 3-acetyl-chlorophyllide a through 3-(1-hydroxyethyl)-chlorophyllide a, indicating that these enzymes work cooperatively to promote efficient bacteriochlorophyll a biosynthesis

physiological function

BchC of Chlorobaculum tepidum preferentially oxidizes porphyrin-type pigments, 31R-3-(1-hydroxyethyl)-chlorophyllide a and 31R-3-(1-hydroxyethyl)-bacteriochlorophyllide a, in the presence of NAD+ to 3-acetylchlorophyllide a and bacteriochlorophyllide a, respectively, leaving the unreacted 31S-epimers. The enzyme catalyzes both the oxidation of 3HE to 3Ac and the reduction of 3Ac to 3HE, the reverse reaction. In the reverse reaction, BchC with NADH predominately produces 31R-epimeric alcohols from the 3-acetyl-(bacterio)chlorins. BchC of Rhodobacter capsulatus demonstrates the same 31R-selectivity, suggesting that utilization of 31R-epimers in BchC-catalyzed reductions may be conserved across different phyla of photosynthetic bacteria
