Crystal structure of the GIY-YIG N-terminal endonuclease domain of UvrC from Thermotoga maritima: Point mutant Y43F bound to its catalytic divalent cationCrystal structure of the GIY-YIG N-terminal endonuclease domain of UvrC from Thermotoga maritima: Point mutant Y43F bound to its catalytic divalent cation
Structural highlights
Function[UVRC_THEMA] The UvrABC repair system catalyzes the recognition and processing of DNA lesions. UvrC both incises the 5' and 3' sides of the lesion. The N-terminal half is responsible for the 3' incision and the C-terminal half is responsible for the 5' incision (By similarity). 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 PubMedNucleotide excision repair is a highly conserved DNA repair mechanism present in all kingdoms of life. The incision reaction is a critical step for damage removal and is accomplished by the UvrC protein in eubacteria. No structural information is so far available for the 3' incision reaction. Here we report the crystal structure of the N-terminal catalytic domain of UvrC at 1.5 A resolution, which catalyzes the 3' incision reaction and shares homology with the catalytic domain of the GIY-YIG family of intron-encoded homing endonucleases. The structure reveals a patch of highly conserved residues surrounding a catalytic magnesium-water cluster, suggesting that the metal binding site is an essential feature of UvrC and all GIY-YIG endonuclease domains. Structural and biochemical data strongly suggest that the N-terminal endonuclease domain of UvrC utilizes a novel one-metal mechanism to cleave the phosphodiester bond.
