Required for resistance to the phenazine antibiotic D-alanylgriseoluteic acid (AGA), an antibiotic produced by E.agglomerans itself, and thus protects the bacterium against phenazine toxicity. Probably binds AGA and acts as a chaperone that works in tandem with a membrane transporter for subsequent antibiotic secretion. Homodimer. Loss of D-alanylgriseoluteic acid resistance.
