obsolete sterol-4-alpha-carboxylate 3-dehydrogenase (decarboxylating) activity https://github.com/geneontology/go-ontology/issues/28070 https://github.com/geneontology/go-ontology/issues/28822 true molecular_function OBSOLETE. Catalysis of the reaction: NAD(P)+ + 3-beta-hydroxy-4-alpha-methyl-5-alpha-cholest-7-ene-4-beta-carboxylate = NAD(P)H + H+ + CO2 + 4-alpha-methyl-5-alpha-cholest-7-en-3-one. GO:0047012 This term was obsoleted because it represents the same function as 3beta-hydroxysteroid-4alpha-carboxylate 3-dehydrogenase (decarboxylating) [NAD(+)] activity ; GO:0102191. 3-beta-hydroxy-4-alpha-methylcholestenecarboxylate 3-dehydrogenase (decarboxylating) activity 3-beta-hydroxysteroid dehydrogenase (NAD+)/C4-decarboxylase activity
