| Description | This entry represents enzymes that perform ADP-ribosylations, including ADP-ribosylhydrolase ARH1/3 from animals, which preferentially hydrolyses the scissile alpha-O-linkage attached to the anomeric C1'' position of ADP-ribose and acts on different substrates, such as proteins ADP-ribosylated on serine and threonine, free poly(ADP-ribose) and O-acetyl-ADP-D-ribose [ , , ].The family also includes ADP-ribosylarginine hydrolase Tri1 from Serratia proteamaculans. This protein neutralises Tre1-Sp both by occluding its active site via its N-terminal extension and by hydrolysing the ADP-ribosyl moiety from FtsZ. It functions as an immunity component of a contact-dependent interbacterial competition system (also called effector-immunity systems) [ ].ADP-ribosyl-[dinitrogen reductase] glycohydrolase is involved in the regulation of nitrogen fixation activity by the reversible ADP-ribosylation of one subunit of the homodimeric dinitrogenase reductase component of the nitrogenase enzyme complex in Rhodospirillum rubrum [, ].Jellyfish Crystallin proteins [ ] are also included in this group, although these proteins appear to have lost the presumed active site residues. | Name | ADP-ribosylation/Crystallin J1 |
