Kinetic properties of tartrate-resistant acid phosphatase isolated from human spleen with leukemic reticuloendotheliosis. 1977

K W Lam, and L C Lai, and P T Burkart, and L T Yam

The tartrate-resistant acid phosphatase was isolated from the spleen of a patient with leukemic reticuloendotheliosis. The unique characteristic of the enzyme is its similar reactivity toward p-nitrophenylphosphate, inorganic pyrophosphate ADP, and ATP. When ATP was incubated with the enzyme, the initial products were ADP and inorganic phosphate. The kinetic data confirmed that these substrates were hydrolyzed by the same enzyme. This type of substrate specificity is clearly different from acid phosphatase and pyrophosphatases previously described in the literature.

D007700 Kinetics The rate dynamics in chemical or physical systems.
D007938 Leukemia A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells.
