case <OC:Methanobacteria> or <OC:Methanococci> or <OC:Methanomicrobia> or <OC:Methanopyri> | |
FUNCTION | Catalyzes the transfer of a methyl group to L-homocysteine resulting in methionine formation. Can use methylcobalamin and methylcobinamide as methyl donors, but methylcobalamin is not considered to be the physiological substrate. |
else | |
FUNCTION | Catalyzes the transfer of a methyl group to L-homocysteine resulting in methionine formation. The physiological methyl donor is unknown. |
