ID   4.2.1.165
DE   chlorophyllide a 3(1)-hydratase.
CA   (1) 3-devinyl-3-(1-hydroxyethyl)chlorophyllide a = chlorophyllide a +
CA   H2O.
CA   (2) 3-deacetyl-3-(1-hydroxyethyl)bacteriochlorophyllide a = 3-deacetyl-3-
CA   vinylbacteriochlorophyllide a + H2O.
CC   -!- The enzyme, together with EC 1.3.7.15 and EC 1.1.1.396, is involved
CC       in the conversion of chlorophyllide a to bacteriochlorophyllide a.
CC   -!- The enzymes can act in multiple orders, resulting in the formation of
CC       different intermediates, but the final product of the cumulative
CC       action of the three enzymes is always bacteriochlorophyllide a.
CC   -!- The enzyme catalyzes the hydration of a vinyl group on ring A,
CC       converting it to a hydroxyethyl group.
