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.

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.
