We did not detect significant AraC-dependent or arabinose-dependent regulation of xylA , a previously described AraC-regulated gene ( 36 ) , nor did we detect binding of AraC upstream of xylA .
We did not detect significant AraC-dependent or arabinose-dependent regulation of xylA , a previously described AraC-regulated gene ( 36 ) , nor did we detect binding of AraC upstream of xylA .
With the exception of xylA , the last AraC-regulated gene to be identified was araJ , more than 30 years ago ( 27 ) .
