Abstrakt: The article discusses the result of a study which analyzed phosphosubstrate catalysis by osteoblast-derived matrix vesicles (MV). It was found that adenosine triphosphate (ATP) is the main substrate hydrolyzed by the wild-type MV and that tissue-nonspecific alkaline phosphatase (TNAP) had the most significant effect on the hydrolysis of substrates. The study concludes that TNAP is an enzyme responsible for hydrolyzing ATP and extracellular inorganic phosphatase.
