methionine adenosyltransferase M-CSA #9 | In biological systems, methyl groups are transferred from a small number of donors to a large number of acceptors. S-adenosylmethionine (AdoMet) is the most widespread of these donors, and is synthesised solely by the action of AdoMet synthase. | Defined by 14 residues: HIS:A-29ASP:A-31LYS:A-32GLU:A-57GLU:A-70LYS:A-181PHE:A-250ASP:A-258ALA:A-259ARG:A-264LYS:A-265LYS:A-285LYS:A-289ASP:A-291 | EC: 2.5.1.6 (PDB Primary Data) |
