CRYSTAL STRUCTURE AND MUTATIONAL STUDY OF RECOR PROVIDE INSIGHT INTO ITS ROLE IN DNA REPAIR

Overview

The crystal structure of the complex formed between Deinococcus, radiodurans RecR and RecO (drRecOR) has been determined. In accordance, with previous biochemical characterisation, the drRecOR complex displays a, RecR:RecO molecular ratio of 2:1. The biologically relevant drRecOR entity, consists of a heterohexamer in the form of two drRecO molecules positioned, on either side of the tetrameric ring of drRecR, with their OB, (oligonucleotide/oligosaccharide-binding) domains pointing towards the, interior of the ring. Mutagenesis studies validated the protein-protein, interactions observed in the crystal structure and allowed mapping of the, residues in the drRecOR complex required for DNA binding. Furthermore, the, preferred DNA substrate of drRecOR was identified as being 3'-overhanging, ... [(full description)]
