| + | [https://www.uniprot.org/uniprot/NTM1A_HUMAN NTM1A_HUMAN] Distributive alpha-N-methyltransferase that methylates the N-terminus of target proteins containing the N-terminal motif [Ala/Pro/Ser]-Pro-Lys when the initiator Met is cleaved. Specifically catalyzes mono-, di- or tri-methylation of exposed alpha-amino group of Ala or Ser residue in the [Ala/Ser]-Pro-Lys motif and mono- or di-methylation of Pro in the Pro-Pro-Lys motif. Some of the substrates may be primed by METTL11B-mediated monomethylation. Responsible for the N-terminal methylation of KLHL31, MYL2, MYL3, RB1, RCC1, RPL23A and SET. Required during mitosis for normal bipolar spindle formation and chromosome segregation via its action on RCC1.<ref>PMID:20481588</ref> <ref>PMID:20668449</ref> <ref>PMID:24090352</ref> | ||

| + | The bisubstrate analogue strategy is a promising approach to develop potent and selective inhibitors for protein methyltransferases. Herein, the interactions of a series of bisubstrate analogues with protein N-terminal methyltransferase 1 (NTMT1) were examined to probe the molecular properties of the active site of NTMT1. Our results indicate that a 2-C to 4-C atom linker enables its respective bisubstrate analogue to occupy both substrate- and cofactor-binding sites of NTMT1, but the bisubstrate analogue with a 5-C atom linker only interacts with the substrate-binding site and functions as a substrate. Furthermore, the 4-C atom linker is the optimal and produces the most potent inhibitor (Ki,app = 130 +/- 40 pM) for NTMT1 to date, displaying more than 3000-fold selectivity for other methyltransferases and even for its homologue NTMT2. This study reveals the molecular basis for the plasticity of the active site of NTMT1. Additionally, our study outlines general guidance on the development of bisubstrate inhibitors for any methyltransferases. | ||
