lldPRD operon promoter + RBS from E. coli
This is the promoter region for the lldPRD operon (previously named lct) of E. coli. The lldPRD operon encodes a lactate-dehydrogenase, and the lldPRD promoter has been shown to be induced by L-lactate.
The promoter is repressed by the regulatory protein lldR encoded by the operon. In the absence of L-lactate, lldR binds to two operator sites O1 and O2 in the promoter region and inhibits expression. [1]
The activity of lldP may be repressed by chloramphenicol and nutrient-rich growth media.
