The amide group of glutamine is a source of nitrogen in the biosynthesis of a variety of
compounds. These reactions are catalyzed by a group of enzymes known as glutamine …

Abstract p-Aminobenzoate synthase (PS) and anthranilate synthase (AS) are structurally
related enzymes that catalyze similar reactions and produce similar products, para-and …

Escherichia coli pabA encodes the glutamine amidotransferase subunit of p-aminobenzoate
synthase. p-Aminobenzoate synthase catalyzes the conversion of chorismate and glutamine …
