Summary
RecBCD is a bipolar helicase. [More information is available at EcoGene: EG10824]. RecB, RecC, and RecD make up a helicase/nuclease complex that is essential for both homologous recombination during the course of transduction and conjugation as well as in repair of double-strand breaks in Escherichia coli . [More information is available at EcoCyc: EG10824].
