Genomic Context

[SW|Categories] containing this gene/protein

• [SW|capsule biosynthesis and degradation]

This gene is a member of the following [SW|regulons]

• [SW|DegU regulon]

Gene

Coordinates on the chromosome (coding sequence): 3,698,982 -> 3,699,431

Phenotypes of a mutant

• no synthesis of the poly-gamma-glutamate capsule [Pubmed|11751809]

Expression and Regulation

Operon

• ''[protein|search|capB]-[protein|search|capC]-[protein|search|capA]-[protein|search|capE]'' [Pubmed|11751809]

[SW|Sigma factor]

• [protein|search|SigA] [Pubmed|19420703]

Regulatory mechanism

• activated by [protein|search|DegU]-P [Pubmed|19420703]

Additional information

• The operon is not expressed in the lab strain 168 due to lack of expression of [protein|search|DegQ] resulting in inactivity of [protein|search|DegS] and [protein|search|DegU] [PubMed|21965392]
• expression of the operon is reduced in '[protein|search|motA]' or '[protein|search|motB]' mutants due to reduced [protein|search|DegU] phosphorylation [PubMed|24296669]
