TL;DR: It is shown that inosine triphosphatase (ITPase) activity catalyzed by F1 from bovine heart mitochondria is much more sensitive to inactivation by 5'-p-fluorosulfonylbenzoyladenosine (FSBA) than is ATPase activity.
TL;DR: Pretherapeutic screening of individuals for ITPA 94C>A polymorphisms in the Japanese population should be considered for safer and more tolerable treatment with thiopurine drugs.
TL;DR: Two ITPA variants were strongly associated with protection against treatment‐related anemia in patients with genotype 2/3 HCV, but they did not decrease the need for RBV dose reduction or increase the rate of SVR.
TL;DR: Reciprocal Michaelis-Menten constants obtained by optical means have been compared with those obtained chemically and some kinetic considerations concerning deformable enzyme systems are explored.
TL;DR: It is argued convincingly that bi-site hydrolysis activity is negligible, and may not even exist, and that only tri-site Hydrolysis drives subunit rotation.
