additional information
in vitro enzymatic hydration of some 3-vinyl-chlorophyll derivatives with usage of zinc complexes of cyclic tetrapyrroles as the enzymatic substrates alternative to chlorophyll(ide)s chelated with magnesium ion. Recombinant BchF catalyzes stereoselective hydration of zinc 3-vinyl-8-ethyl-12-methyl-bacteriopheophorbide c or d to the zinc 31R-bacteriopheophorbide c or d homologue, respectively. The enzymatic hydration for the 8-propylated substrate proceeds more slowly than that for the 8-ethylated, and the 8-isobutylated substrate is no longer hydrated. The wild-type strain of Chlorobaculum tepidum gives almost exclusively 31R-epimers of 8-ethyl-12-methyl- and 8,12-diethyl-BChl c, approximately 90% 31R- and 10% 31S-epimers of 8-propyl-12-ethyl-BChl c, and entirely 31S-epimer of 8-isobutyl-12-ethyl-BChl c: 4% 31S-epimers in the total amount of BChl c homologues. The in vivo hydrations might be effective even after the 20-methylation by a methyltransferase, BchU. No activity of BchF in the hydration of the 3-vinyl group of protochlorophyllide a, the porphyrin form of chlorophyllide a. The hydrogenation of the porphyrin to chlorin Pi-system is necessary for the substrate of BchF hydration. In all the BchF-catalyzed reactions, the products are mixtures of the 31R- and 31S-epimers, and the R-epimers are mainly obtained with a lower amount of the S-epimers. The 20-methylated analogue of Zn-3V[E,M]BPheide d, Zn-3V[E,M]BPheide c, is hydrated by BchF and BchV enzymes to give Zn-[E,M]BPheide c

deletion of bchF gene affects the composition of 31R/S-epimers in composite BChls c, the bchF-deleted mutant has nearly 100% R-stereochemistry in 8-ethyl-12-methyl- and 8,12-diethyl-BChls c, 9-12% S-stereochemistry in 8-propyl-12-ethyl-BChl c, and nearly 100% S-stereochemistry in 8-isobutyl-12-ethyl-BChl c; deletion of bchV gene affects the composition of 31R/S-epimers in composite BChls c, the bchV-deleted mutant has nearly 100% R-stereochemistry in 8-ethyl-12-methyl- and 8,12-diethyl-BChls c, 0-6% S-stereochemistry in 8-propyl-12-ethyl-BChl c, and very few 8-isobutyl-12-ethyl-BChl c

additional information
the central metal is essential for the BchF reaction. Since the 132-methoxycarbonyl group in substrates is not necessary for the enzymatic reactions, the free 172-carboxy group and the central magnesium ion of chlorins are important for the substrates of hydration by BchF enzyme; the central metal is essential for the BchV reaction. Since the 132-methoxycarbonyl group in substrates is not necessary for the enzymatic reactions, the free 172-carboxy group and the central magnesium ion of chlorins are important for the substrates of hydration by BchV enzyme
