1. Serine transacetylase, O-acetylserine sulphydrylase and beta-cystathionase were purified from Paracoccus denitrificans strain 8944. 2. Serin transacetylase was purified 150-fold. The enzyme has a pH optimum between 7.5 and 8.0, is specific for L-serine and is inhibited by sulphydryl-group reagents. The apparent Km values for serine and acetyl-CoA are 4.0 - 10(-4) and 1.0 - 10(-4) M, respectively. Serine transacetylase is strongly inhibited by cysteine. 3. O-Acetylserine sulphydrylase was… CONTINUE READING
