Transcription factor that regulates the expression of several genes involved in the transport and metabolism of L-arabinose (PubMed:4362626, PubMed:328165, PubMed:6251457, PubMed:2962192, PubMed:6319708, PubMed:2231717, PubMed:1447222). Functions both as a positive and a negative regulator (PubMed:328165, PubMed:6251457). In the presence of arabinose, activates the expression of the araBAD, araE, araFGH and araJ promoters (PubMed:4362626, PubMed:328165, PubMed:6251457, PubMed:2962192, PubMed:6319708, PubMed:2231717, PubMed:1447222). In the absence of arabinose, negatively regulates the araBAD operon (PubMed:6251457). Represses its own transcription (PubMed:328165). Acts by binding directly to DNA (PubMed:4943786, PubMed:6251457, PubMed:2962192, PubMed:2531226, PubMed:1447222).
