ADP-ribosylarginine hydrolase Tri1

UniProtKB accession:  A8GG79

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Immunity component of a contact-dependent interbacterial competition system (also called effector-immunity systems). Acts as an arginine mono-ADP-ribosylhydrolase, mediating the removal of mono-ADP-ribose attached to arginine residues on proteins. De-ADP-ribosylates FtsZ, is able to act on other proteins as well. Neutralizes the toxic activity of cognate toxin Tre1-Sp. Expression of this protein alone in E.coli partially protects the cells against competition by wild-type S.proteamaculans. Neutralizes Tre1-Sp both by occluding its active site via its N-terminal extension and by hydrolyzing the ADP-ribosyl moiety from FtsZ; the 2 activities are dissociable by mutagenesis.
