WebStructure. L-arabinose operon is composed of structural genes and regulatory regions including the operator region (araO 1, araO 2) and the initiator region (araI 1, araI 2).The structural genes, araB, araA and araD, encode enzymes for L-arabinose catabolism.There is also a CAP binding site where CAP-cAMP complex binds to and facilitates catabolite … WebDec 1, 1999 · A dose-response and time course analysis of l-arabinose induction of cat expression.
