Function
PAP_BACSU Catalyzes the specific dephosphorylation of phosphoarginine residues in a large number of proteins. Counteracts the protein arginine kinase McsB in vivo. Can dephosphorylate CtsR-P; thus, can restore the DNA-binding ability of the CtsR repressor by reversing the McsB-mediated phosphorylation. Is the only active pArg phosphatase present in B.subtilis. Exhibits almost no activity against pSer, pThr, or pTyr peptides. Appears to play a role in B.subtilis stress resistance. 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.[1] [2] [3]
Publication Abstract from PubMed
Many cellular pathways are regulated by the competing activity of protein kinases and phosphatases. The recent identification of arginine phosphorylation as a protein modification in bacteria prompted us to analyze the molecular basis of targeting phospho-arginine. In this work, we characterize an annotated tyrosine phosphatase, YwlE, that counteracts the protein arginine kinase McsB. Strikingly, structural studies of YwlE reaction intermediates provide a direct view on a captured arginine residue. Together with biochemical data, the crystal structures depict the evolution of a highly specific phospho-arginine phosphatase, with the use of a size-and-polarity filter for distinguishing phosphorylated arginine from other phosphorylated side chains. To confirm the proposed mechanism, we performed bioinformatic searches for phosphatases, employing a similar selectivity filter, and identified a protein in Drosophila melanogaster exhibiting robust arginine phosphatase activity. In sum, our findings uncover the molecular framework for specific targeting of phospho-arginine and suggest that protein arginine (de)phosphorylation may be relevant in eukaryotes.
