Protein
Putative acyl-CoA dehydrogenase AidB
Organism
Escherichia coli (strain K12)
Function
Part of the adaptive DNA-repair response to alkylating agents. Could prevent alkylation damage by protecting DNA and destroying alkylating agents that have yet to reach their DNA target. Binds to double-stranded DNA with a preference for a DNA region that includes its own promoter. Shows weak isovaleryl-CoA dehydrogenase activity in vitro.
Similarity
Belongs to the acyl-CoA dehydrogenase family.
