MAP1B_ARATH - PTM Information in dbPTM

Basic Information of Protein

• UniProt ID: MAP1B_ARATH
• UniProt AC: Q9FV52
• Protein Name: Methionine aminopeptidase 1B, chloroplastic {ECO:0000255|HAMAP-Rule:MF_03174}
• Gene Name: MAP1B
• Organism: Arabidopsis thaliana (Mouse-ear cress).
• Sequence Length: 369
• Subcellular Localization: Plastid, chloroplast .
• Protein Description: Removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val)..
