Organism
Deinococcus radiodurans (strain ATCC 13939 / DSM 20539 / JCM 16871 / LMG 4051 / NBRC 15346 / NCIMB 9279 / R1 / VKM B-1422)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Can catalyze the hydrolysis of ATP in the presence of single-stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage (By similarity). Probably involved in base excision repair (PubMed:19303848).UniRule annotation1 Publication
Following severe irradiation (7 kGy of gamma irradiation) genomic DNA is fragmented. DNA is progressively degraded for the first 1.5 hours after IR, in a step promoted by RecA and counterbalanced by DNA Pol I and Pol III, followed by massive DNA synthesis and genome reassembly in the next hour. Optimal priming of DNA synthesis requires both RecA and RadA, Pol III initiates DNA synthesis while both Pol I and Pol III are required for its contination. In the absence of RecA the majority of the chromosome is still reconstituted, via either single-strand annealing or non-homologous end joining (PubMed:19303848).1 Publication

Disruption phenotypei

Reduced DNA synthesis rate even in the absence of ionizing radiation (IR) (PubMed:19303848). Cells lacking this gene have a reduced capacity to survive IR (from 90% survival to <10(-7)), DNA repair following IR is slow (PubMed:20451472, PubMed:19303848). Single recA mutants rarely reconstitutes the whole genome following IR, and their DNA is not degraded post-IR (PubMed:19303848). A double recA-ddrB disruption shows no signs of DNA repair 24 hours after IR (PubMed:20451472). Double recA-radA deletion mutants have a more severe effect than either mutation alone after IR (PubMed:19303848).2 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
