2.1.1.202 additional information the S-adenosyl-L-methionine analigue sinefungin is bound in a negatively charged pocket near helix alpha8, binding structure, detailed overview 719968 2.1.1.202 S-adenosyl-L-methionine - 735680, 735864, 735907, 736856, 737227, 756866, 757702, 757846, 757867, 758103, 758477 2.1.1.202 S-adenosyl-L-methionine cofactor interacting residues in hNSun6 are mainly composed of conserved residues Leu241, Cys242, Pro325 and Leu354. In addition, the side chain of residue Asp293 recognizes the N6 of the adenine ring. Asp293 is conserved as Asp or Glu in the RNA:m5C MTase family 757846 2.1.1.202 S-adenosyl-L-methionine helix alpha8 can adopt two different conformations, thereby controlling the entry of S-adenosyl-L-methionine into the active site 719968
