xylR+PxylA: A xylose inducible promoter with its transcriptional regulator.


This part is extracted by PCR from pAX01 plasmid. (Zeigler 2002)In the region of PxylA, there are two promoters with opposite directions: one regulates the expression of xylR, and another one is regulated by xylR. (Rygus et al., 1991) When xylR is expressed, it will inhibit the expression of the gene on the downstream of PxylA. However, without xylR, PxylA can be regarded as a constitutive promoter. Besides, upon the induction of xylose, the transcriptional regulator will not bind to the binding site in the promoter region, and transcription will start.
