title: Hypersensitivity to catabolite repression in the L-arabinose operon of Escherichia coli B/r is trans acting.
abstract: Mutations causing hypersensitivity to catabolite repression have been assigned to gene araC (activator protein) by complementation analysis. The araO (operator region) is non-essential for catabolite repression.
