Structure of mouse ADP-ribosylhydrolase 3 (mARH3)
نویسندگان
چکیده
ADP-ribosylation is a reversible and covalent post-translational modification in which the attachment of ADP-ribose is catalyzed by ADP-ribosyltransferases and the removal of ADP-ribose is catalyzed by ADP-ribosylhydrolases. ADP-ribosylhydrolase 3 from mouse, consisting of 347 amino-acid residues, has been cloned, purified and crystallized. The three-dimensional structure has been resolved at a resolution of 1.8 A. The structure constitutes a compact all-alpha-helical protein with two Mg(2+) ions located in the active-site crevice. A structural comparison of mouse ADP-ribosylhydrolase 3 with its human orthologue shows a high degree of structural similarity. Furthermore, four prokaryotic proteins deposited in the PDB could be identified as being structurally related.

Protein-reversible ADP-ribosylation is emerging as an important post-translational modification used to control enzymatic and protein activity in different biological systems. This modification regulates nitrogenase activity in several nitrogen-fixing bacterial species. ADP-ribosylation is catalyzed by ADP-ribosyltransferases and is reversed by ADP-ribosylhydrolases. The structure of the ADP-ri...
متن کاملThe structure of human ADP-ribosylhydrolase 3 (ARH3) provides insights into the reversibility of protein ADP-ribosylation.
Posttranslational modifications are used by cells from all kingdoms of life to control enzymatic activity and to regulate protein function. For many cellular processes, including DNA repair, spindle function, and apoptosis, reversible mono- and polyADP-ribosylation constitutes a very important regulatory mechanism. Moreover, many pathogenic bacteria secrete toxins which ADP-ribosylate human pro...

Adprhl1, a member of the ADP-ribosylhydrolase protein family, is expressed exclusively in the developing heart of all vertebrates. In the amphibian Xenopus laevis, distribution of its mRNA is biased towards actively growing chamber myocardium. Morpholino oligonucleotide-mediated knockdown of all Adprhl1 variants inhibits striated myofibril assembly and prevents outgrowth of the ventricle. The r...
متن کاملATM induces MacroD2 nuclear export upon DNA damage
ADP-ribosylation is a dynamic post-translation modification that regulates the early phase of various DNA repair pathways by recruiting repair factors to chromatin. ADP-ribosylation levels are defined by the activities of specific transferases and hydrolases. However, except for the transferase PARP1/ARDT1 little is known about regulation of these enzymes. We found that MacroD2, a mono-ADP-ribo...
متن کاملHydrolysis of O-acetyl-ADP-ribose isomers by ADP-ribosylhydrolase 3.
O-acetyl-ADP-ribose (OAADPr), produced by the Sir2-catalyzed NAD(+)-dependent histone/protein deacetylase reaction, regulates diverse biological processes. Interconversion between two OAADPr isomers with acetyl attached to the C-2″ and C-3″ hydroxyl of ADP-ribose (ADPr) is rapid. We reported earlier that ADP-ribosylhydrolase 3 (ARH3), one of three ARH proteins sharing structural similarities, h...
