Connelly, JC and Leach, DR (1996) The sbcC and sbcD genes of Escherichia coli encode a nuclease involved in palindrome inviability and genetic recombination. Genes Cells 1:285-91

Abstract

Long DNA palindromes have the potential to adopt hairpin or cruciform secondary structures that inhibit DNA replication. In Escherichia coli, this palindrome-mediated inviability results from the activity of the sbcC and sbcD genes, and genetic observations have suggested that they may encode a nuclease. Mutations in these genes also restore the defect in genetic recombination associated with recBC sbcB mutants.
