In Vitro Hydrolysis of Zinc Chlorophyllide a Homologues by a BciC Enzyme
Chlorosomes in green photosynthetic bacteria are the largest and most efficient light-harvesting antenna systems of all phototrophs. The core part of chlorosomes consists of bacteriochlorophyll c, d, or e molecules. In their biosynthetic pathway, a BciC enzyme catalyzes the removal of the C13(2)-methoxycarbonyl group of chlorophyllide a. In this study, the in vitro enzymatic reactions of chlorophyllide a analogues, C13(2)-methylene- and ethylene-inserted zinc complexes, were examined using a BciC protein from Chlorobaculum tepidum. As the products, their hydrolyzed free carboxylic acids were observed without the corresponding demethoxycarbonylated compounds. The results showed that the in vivo demethoxycarbonylation of chlorophyllide a by an action of the BciC enzyme would occur via two steps: (1) an enzymatic hydrolysis of a methyl ester at the C13(2)-position, followed by (2) a spontaneous (nonenzymatic) decarboxylation in the resulting carboxylic acid.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 4341-76-8, you can contact me at any time and look forward to more communication. Category: esters-buliding-blocks.
