CRP* is a modified CRP to not require cAMP. Crp is a dual transcriptional regulator that belongs to the CRP family. It is the major global regulator of catabolite-sensitive operons and it controls its own synthesis. This regulator induces a severe bend in the DNA and is capable of regulating the expression of more than 200 genes.

The xylose A promoter is activated by xylR-xylose, and may be negatively regulated by xylR. Two xylR halfsites are included as well as a CRP activator binding site.

The xylose A promoter is activated by xylR-xylose, and may be negatively regulated by xylR. Two xylR halfsites are included, but the promoter region was cloned without the CRP binding site. Note: the removal of CRP may keep the promoter from working unless.
