Protein: Alpha N-terminal protein methyltransferase 1 (EC 2.1.1.244) (Translation associated element 1) (X-Pro-Lys N-terminal protein methyltransferase 1) (NTM1) (O13748)
Organism: Schizosaccharomyces pombe (strain 972 / ATCC 24843) (Fission yeast)
Function: 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 (By similarity).
Subcellular location: Cytoplasm {ECO:0000250}.
