Phenotypes of a mutant
in an ''mfd'' knock-out, the cell's ability to accumulate adaptive mutations in stationary phase is depressed [http://www.pubmed.com/16950921 PubMed]
strongly reduced stationary phase mutagenesis [Pubmed|27399782]
increased UV-induced mutagenesis via [[protein|PolY1]]/ [[protein|PolY2]]-mediated translesion synthesis [Pubmed|24118570]
the mutation suppresses the mucoid phenotype of ''[[gene|motA]]'' or ''[[gene|motB]]'' mutants [Pubmed|24296669]

The protein
Catalyzed reaction/ biological activity
promotes strand-specific DNA repair by displacing [SW|RNA polymerase] stalled at a nucleotide lesion and directing the (A)BC excinuclease to the RNA damage site
is required for roadblock transcription repression by transcription factors with binding sites downstream of the promoter (as for [[protein|CcpA]] [Pubmed|9535092] and [[protein|CodY]] [Pubmed|21699902])
required for the processing of genetic damage during [SW|sporulation] [Pubmed|24118570]
