Escherichia coli K-12 substr. MG1655 Polypeptide: DNA recombination protein



Gene: radA Accession Numbers: EG11296 (EcoCyc), b4389, ECK4381

Synonyms: sms

Regulation Summary Diagram: ?

Summary:
RadA is involved in processing of DNA recombination intermediates [Beam02].

A radA mutant exhibits a conjugational DNA recombination defect [Beam02]. A radA mutant exhibits greater sensitivity to methylmethane sulfonate [Neuwald92, Song96, Beam02], phleomycin [Beam02], or to UV irradiation than wild type [Song96]. RadA exhibits genetic interactions with a number of recombination genes that indicate a role in processing of DNA recombination intermediates [Beam02].

RadA has a zinc finger motif (CX2CXnCX2C) [Neuwald92]. RadA has an ATP/GTP-binding motif [Neuwald92].

RadA has similarity to Lon and RecA [Neuwald92]. RadA also has similarity to a Bacillus subtilis DNA recombination protein [Kruger97].

Regulation has been described [Neuwald92]. The serB and radA genes are in the same operon [Neuwald92].
