IUBMB Comments
This enzyme, found in green sulfur bacteria (Chlorobiaceae) and green filamentous bacteria (Chloroflexaceae), catalyses the first committed step in the biosynthesis of bacteriochlorophylls c, d, and e, the removal of the C-132-methylcarboxyl group from chlorophyllide a. The reaction is very similar to the conversion of pheophorbide a to pyropheophorbide a during chlorophyll a degradation, which is catalysed by EC 3.1.1.82, pheophorbidase.
