Comments [?]

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.
end case
Cofactor Zn(2+)
Note: Binds 1 zinc ion per subunit.
Pathway Amino-acid biosynthesis; L-methionine biosynthesis via de novo pathway.
Similarity Belongs to the archaeal MetE family.
