[Properties of NAD-pyrophosphorylase of the nuclei of liver cells of chickens].
Certain characteristics of chicken liver cells nuclei NAD-pyrophosphorylase (NMN-adenylytranspherase, EC 2.7.7.1) were investigated. It was established that NAD-pyrophosphorylase activity optimum pH is within interval of 7.0-7.5; temperature optimum - 38-39 degrees C; factor Q10 is equal to 2. Enzyme activation energy, inactivation energy and enthalpy were calculated; apparent Km values of NAD-pyrophosphorylase with respect to NMN and ATP are equal to 1.62-10(-7) M and 2.61-10(-7) M, respectively.
