THE CATALYTIC FRAGMENT OF POLY(ADP-RIBOSE) POLYMERASE

Structural highlights

2paw is a 1 chain structure with sequence from Chick. This structure supersedes the now removed PDB entry 1paw. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Activity:	NAD(+) ADP-ribosyltransferase, with EC number 2.4.2.30
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum

Function

[PARP1_CHICK] Poly[ADP-ribose] polymerase modifies various nuclear proteins by poly(ADP-ribosyl)ation. The modification is dependent on DNA and is involved in the regulation of various important cellular processes such as differentiation, proliferation, and tumor transformation and also in the regulation of the molecular events involved in the recovery of cell from DNA damage.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.

Publication Abstract from PubMed

Inhibitors of poly(ADP-ribose) polymerase (PARP, EC 2.4.2.30) are of clinical interest because they have potential for improving radiation therapy and chemotherapy of cancer. The refined binding structures of four such inhibitors are reported together with the refined structure of the unligated catalytic fragment of the enzyme. Following their design, all inhibitors bind at the position of the nicotinamide moiety of the substrate NAD+. The observed binding mode suggests inhibitor improvements that avoid other NAD(+)-binding enzymes. Because the binding pocket of NAD+ has been strongly conserved during evolution, the homology with ADP-ribosylating bacterial toxins could be used to extend the bound nicotinamide, which is marked by the inhibitors, to the full NAD+ molecule.
