A substrate analogue study on clavaminic acid synthase: possible clues to the biosynthetic origin of proclavamic acid
Abstract
Incubation of (2S)-5-amino-(2′-oxoazetidin-1′-yl)pentanoic acid with clavaminic acid synthase gave (2S)-5-amino-2-(2′-oxoazetidin-1′-yl)pent-3,4-enoic acid as the major product, together with a small amount of proclayaminic acid; modification of the amino group to the guanyl group biased the mode of reactivity from desaturation to hydroxylation.
