WebThe cloned ara fragments were identified by both physical and genetic tests. A restriction map was constructed and the DNA sequence of the promoter was determined. The … WebJul 1, 1996 · The DNA contains no obvious −10 and −35 sequences other than those at the ara PBAD promoter. Secondary polymerase binding sites have been observed near some promoters and their presence has complicated data interpretation ( 9–11). For the experiments done with ara two such sites, at positions −64 and −96, had been removed ( 1).

Continued on next page . 2 Overview, continued Experimental The L-arabinose operon, also called the ara or araBAD operon, is an operon required for the breakdown of the five-carbon sugar L-arabinose in Escherichia coli. The L-arabinose operon contains three structural genes: araB, araA, araD (collectively known as araBAD), which encode for three metabolic enzymes … See more L-arabinose operon is composed of structural genes and regulatory regions including the operator region (araO1, araO2) and the initiator region (araI1, araI2).
