ENZYME entry: EC 3.1.1.100

Accepted Name
Chlorophyllide a hydrolase.
Alternative Name(s)
BciC (gene name).
Reaction catalysed
Chlorophyllide a + H(2)O <=> 8-ethyl-12-methyl-3-vinyl-bacteriochlorophyllide d + methanol + CO(2)
Comment(s)
  • This enzyme, found in green sulfur bacteria (Chlorobiaceae) and green filamentous bacteria (Chloroflexaceae), catalyzes the first committed step in the biosynthesis of bacteriochlorophylls c, d and e, the removal of the C-13(2)-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 catalyzed by EC 3.1.1.82.
