Reactions
4 H2O + 3 NADP+ + CO2 + Lathosterol = 3 NADPH + 3 Oxygen + 3 H+ + Methostenol
NAD+ + 3beta-Hydroxy-4beta-methyl-5alpha-cholest-7-ene-4alpha-carboxylate = NADH + CO2 + H+ + 4alpha-Methyl-5alpha-cholest-7-en-3-one
NADP+ + 3beta-Hydroxy-4beta-methyl-5alpha-cholest-7-ene-4alpha-carboxylate = NADPH + CO2 + H+ + 4alpha-Methyl-5alpha-cholest-7-en-3-one
NADP+ + 4alpha-Methylzymosterol-4-carboxylate = NADPH + CO2 + H+ + 3-Keto-4-methylzymosterol
