Viral adenosine triphosphatase [PDF]
The catalytic and immunological properties of an adenosine triphosphatase from different types of virus have been studied. The avian myeloblastosis virus has been found to be specialized in holding this enzyme in a highly active state as compared to other virus with respect to their host cell enzyme.

Brain capillary guanosine triphosphatase: A distinction from adenosine triphosphatase
Experientia, 1980Differences in kinetic properties, pH response, sensitivity to ouabain, and disc-acrylamide electrophoresis resolution, are observed when GTP and ATP are used as the substrates for triphosphohydrolases in isolated rat brain microvessels. In brain parenchyma there are no such differences.

Adenosine triphosphatase in the phloem of Cucurbita
Planta, 1973The distribution of adenosine triphosphatase (ATPase) activity in the phloem of petioles and minor veins of Cucurbita maxima has been studied using a lead phosphate precipitation procedure. ATPase activity was localized in sieve elements, companion cells and parenchyma cells.

Thiamine triphosphatase in the nervous system
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1972Abstract Thiamine triphosphate is hydrolyzed by a specific triphosphatase in subcellular fractions of rat brain. This enzyme differs from nucleoside triphosphatases in (1) its subcellular distribution pattern; (2) its susceptibility to inhibition by Ca 2+ ; (3) its activation by sodium deoxycholate; (4) its failure to be affected by known inhibitors ...

The adenosine triphosphatase activity of the meromyosins
Biochimica et Biophysica Acta (BBA) - Enzymology, 1967Abstract 1. 1.|Mg 2+ does not activate the ATPase (ATP phosphohydrolase, EC 3.6.1.3) of actin-heavy meromyosin complex (acto-HMM) at low ionic strength. 2. 2.|The interaction inhibitor heparin, which dissociates actomyosin and inhibits its ATPase activity, also inhibits the ATPase of acto-HMM. 3.
