Fig. 3From: Highly efficient preparation of active S-phenyl-L-cysteine with tryptophan synthase using a chemoenzymatic methodEffect of temperature on the tryptophan synthase-catalysed synthesis of S-phenyl-L-cysteine. Tryptophan synthase was directly mixed with the substrate (180 mmol/L) at pH 9.0 for 14 h using Trion X-100 at 0.02%Back to article page
