Protein-arginine-phosphatase

UniProtKB accession:  S0F332

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the specific dephosphorylation of phosphoarginine residues in proteins. Probably counteracts the protein arginine kinase McsB in vivo. Exhibits almost no activity against pTyr peptides. Protein arginine phosphorylation has a physiologically important role and is involved in the regulation of many critical cellular processes, such as protein homeostasis, motility, competence, and stringent and stress responses, by regulating gene expression and protein activity.
