Alpha N-terminal protein methyltransferase 1

UniProtKB accession:  P38340

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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. Responsible for the N-terminal methylation of the ribosomal proteins RPL12A, RPL12B, RPS25A and RPS25B.
