mechanism: the bound S-adenosyl-L-methionine is firmly connected to protein and a Gly pocket" is created near the bound S-adenosyl-L-methionine. The second substrate Gly binds to Arg175 and is brought into the Gly pocket. Five hydrogen bonds connect the Gly in the proximity of the bound S-adenosyl-L-methionine and orient the lone pair orbital on the amino nitrogen of Gly towards the donor methyl group of S-adenosyl-L-methionine. Thermal motion of the enzyme leads to a collision of the N and C(E) so that a SN2 methyltransfer reaction occurs
