S-Adenosylmethionine 171-191 eukaryotic translation elongation factor 2 Homo sapiens 243-246 24422557-3 2014 The first step is the transfer of the 3-amino-3-carboxypropyl group from S-adenosyl-l-methionine (SAM) to the histidine residue of EF2, forming a C-C bond. S-Adenosylmethionine 98-101 eukaryotic translation elongation factor 2 Homo sapiens 131-134 24422557-3 2014 The first step is the transfer of the 3-amino-3-carboxypropyl group from S-adenosyl-l-methionine (SAM) to the histidine residue of EF2, forming a C-C bond. S-Adenosylmethionine 73-96 eukaryotic translation elongation factor 2 Homo sapiens 131-134
