ID   1.1.1.418
DE   plant 3beta-hydroxysteroid-4alpha-carboxylate 3-dehydrogenase
DE   (decarboxylating).
AN   3beta-hydroxysteroid dehydrogenases/C-4 decarboxylase.
CA   a 3beta-hydroxysteroid-4alpha-carboxylate + NAD(+) = a 3-oxosteroid +
CA   CO2 + NADH.
CC   -!- The enzyme, found in plants, catalyzes multiple reactions during
CC       plant sterol biosynthesis.
CC   -!- Unlike the fungal/animal enzyme EC 1.1.1.170 the plant enzyme is
CC       specific for NAD(+).
