IUBMB Enzyme Nomenclature


Accepted name: protein arginine phosphatase

Reaction: a [protein]-Nω-phospho-L-arginine + H2O = a [protein]-L-arginine + phosphate

Other name(s): YwlE

Systematic name: [protein]-Nω-phospho-L-arginine phosphohydrolase

Comments: The enzyme, characterized from Gram-positive bacteria, hydrolyses the phosphoramidate (P-N) bond of Nω-phospho-L-arginine residues in proteins and peptides that were phosphorylated by EC, protein-arginine-kinase.
