Phenotypes of a mutant
the mutation suppresses the mucoid phenotype of ''[protein|search|motA]'' or ''[protein|search|motB]'' mutants due to loss of [protein|search|DegU] phosphorylation and concomitant reduced expression of the ''[protein|search|capB]-[protein|search|capC]-[protein|search|capA]-[protein|search|capE]'' operon [Pubmed|24296669]The protein
Catalyzed reaction/ biological activity
