Single-stranded DNA-binding protein DdrB

UniProtKB accession:  Q9RY80

Grouped By:  Matching UniProtKB accession

UniProtKB description:  ssDNA-binding protein that contributes to the ionizing radiation resistance of D.radiodurans. Plays a role in DNA repair and genome reconstitution in a RecA-independent process. Required for recovery from severe genomic fragmentation as a result of exposure to severe levels of ionizing radiation. Binds ssDNA but not dsDNA. Stimulates annealing of complementary ssDNA. Does not complement an ssb disruption.
