Crystal structure of DdrB from Deinococcus radiodurans bound to ssDNA
Template:ABSTRACT PUBMED 23975200
Function
[DDRB_DEIRA] ssDNA-binding protein that contributes to the ionizing radiation resistance of D.radiodurans. Appears to play a role in DNA repair and genome reconstitution, in a RecA-independent process, and is necessary for recovery from severe genomic fragmentation as a result of exposure to severe levels of ionizing radiation. Binds single-stranded DNA but not duplex DNA.[1] [2]
About this Structure
4hqb is a 7 chain structure with sequence from "micrococcus_radiodurans"_raj_et_al._1960 "micrococcus radiodurans" raj et al. 1960. Full crystallographic information is available from OCA.
