New wine from old barrels

Research output: Contribution to journalShort survey

Abstract

Phosphoribosylanthranilate isomerase (PRAI) and indole-3-glycerol phosphate synthase (IGPS) are distantly related α/β-barrel enzymes that catalyze successive steps in tryptophan biosynthesis. A 'new' PRAI was evolved from an 'old' IGPS by random mutagenesis followed by DNA shuffling and in vivo selection.
