Transcription factors of the LacI family

From SubtiWiki
Jump to: navigation, search

These transcription factors resemble the E. coli Lac repressor (LacI). They are involved in the control of sugar catabolic operons in response to the availability of the carbon source. CcpA is the pleiotropic regulator of carbon catabolite repression.
