EC 3.1.1.100
Names
Accepted name:
chlorophyllide a hydrolase
Other
name:
bciC (gene name)
Systematic name:
chlorophyllide-a hydrolase
Reaction
- chlorophyllide a + H2O = 8-ethyl-12-methyl-3-vinyl-bacteriochlorophyllide d + methanol + CO2
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.
