Evidence that expression of the Vibrio vulnificus hemolysin gene is dependent on cyclic AMP and cyclic AMP receptor protein

J Bacteriol. 1999 Dec;181(24):7639-42. doi: 10.1128/JB.181.24.7639-7642.1999.

Abstract

Glucose repressed hemolysin production in Vibrio vulnificus. Promoter activity of the hemolysin gene, vvh, assessed with a vvh-luxCDABE transcriptional fusion, required cyclic AMP (cAMP) and cAMP receptor protein (CRP) in Escherichia coli. Hemolysin production in V. vulnificus increased after the addition of cAMP and was undetectable in a putative crp mutant, suggesting that vvh is also regulated by cAMP-CRP in V. vulnificus.
