DE   chlorophyllide a hydrolase.
AN   bciC (gene name).
CA   chlorophyllide a + H(+) + H2O = 8-ethyl-12-methyl-3-
CA   vinylbacteriochlorophyllide d + CO2 + methanol.
CC   -!- This enzyme, found in green sulfur bacteria (Chlorobiaceae) and green
CC       filamentous bacteria (Chloroflexaceae), catalyzes the first committed
CC       step in the biosynthesis of bacteriochlorophylls c, d and e,
CC       the removal of the C-13(2)-methylcarboxyl group from chlorophyllide
CC       a.
CC   -!- The reaction is very similar to the conversion of pheophorbide a to
CC       pyropheophorbide a during chlorophyll a degradation, which is
CC       catalyzed by EC 3.1.1.82.
