all known substrates of NTMT1 contain the N-terminal consensus sequence XPK (X = S/P/A/G), although NTMT1 can also methylate peptides with X being F, Y, C, M, K, R, N, Q, or H in vitro, substrate specificity of NTMT1, overview. Structural basis for the specific N-terminal methylation of a consensus motif, XPK, by NTMT1, overview. Hexapeptides composed of the first six residues of RCC1, i.e. regulator of chromosome condensation 1, are recognized by the enzyme. The first residue within the consensus sequence of the NTMT1 substrates is anchored through a hydrogen bond with the conserved Asn168 of NTMT1 in a spacious binding pocket, which exposes the substrate's reactive alpha-amino group to S-adenosyl-L-methionine in the complex structures, and this very N-terminal residue can tolerate most residue substitutions except the negatively charged residues D and E. Asp180 and His140 can act as bases to facilitate deprotonation of the target alpha-N-terminal amino group. Catalytic reaction proceeds probably involving a SN1 mechanism, overview
S-adenosyl-L-homocysteine is bound to NTMT1 in an extended conformation. The carboxylate moiety of SAH forms a salt bridge interaction with the highly conserved Arg74, and the ribosyl group stacks with the indole ring of Trp20. In addition, the adenine moiety of SAH is flanked by the hydrophobic side chains of Ile92 and Val137 and interacts with the main chain amide group of Leu119 and the side chain of Gln120 through hydrogen bonding
