Studies on the stereospecificity of the clavaminic acid synthase catalysed hydroxylation reaction
Abstract
Incubation of (2S,3S)-5-guanidino[2,3-2H2]-2-(2′-oxoazetidin-1′-yl)pentanoic acid and (2S,3R)-5-guanidino-[3-2H1]-2-(2′-oxoazetidin-1′-yl)pentanoic acid with clavaminic acid synthase resulted in highly stereospecific hydroxylation at C-3, with removal of the pro-R hydrogen or deuterium, respectively.
