enzyme catalyzes both the reactions of EC 2.1.1.142, cycloartenol 24-C-methyltransferase and EC 2.1.1.143, 24-methylenesterol C-methyltransferase. SMT1 catalyzes a sterol methylation pathway by the algal Delta25(27)-olefin route, where methylation proceeds by a conserved SN2 reaction and deprotonation proceeds from the pro-Z methyl group on lanosterol corresponding to C27 |
