Expression and Regulation

Operon

• ''txpA'' [Pubmed|16166525]

[SW|Sigma factor]

• [protein|search|SigA] [Pubmed|16166525]

Regulatory mechanism

• expression is prevented by the ''[protein|search|ratA]'' antisense RNA [Pubmed|16166525]
• the ''[protein|search|txpA]'' mRNA-''[protein|search|RatA]'' RNA duplex is degraded by [rnc|search|RNase III] [Pubmed|23300471]

Additional information

• next to '[protein|search|yonT]', the '[protein|search|txpA]' mRNA has the strongest Shine-Dalgarno region in 'B. subtilis' [PubMed|19210617]
