The ions with a tetraedric structure (arsenate, phosphate, sulfate) act as competitive inhibitors of the transketolase-catalyzed reaction. xylulose-5-phosphate 102-122 transketolase Rattus norvegicus 247-260 10080-7 1976 For the transketolase substrates, ribose 5-phosphate and xylulose 5-phosphate, the apparent Km values were 0.3 and 0.5 mM, respectively, in both liver and hepatoma. xylulose-5-phosphate 57-77 transketolase Rattus norvegicus 8-21 7423874-1 1980 Inhibition of rat liver transketolase under conditions of hydroxythiamin or alimentary B1 avitaminosis was accompanied by an increase in intracellular concentration of 6-phosphogluconate and xylulose-5-phosphate. xylulose-5-phosphate 191-211 transketolase Rattus norvegicus 24-37
