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.
对鸡肝细胞细胞核的NAD-焦磷酸化酶（NMN-腺苷酸转移酶，EC 2.7.7.1）的某些特性进行了研究。结果表明，NAD-焦磷酸化酶活性的最适pH在7.0 - 7.5范围内；最适温度为38 - 39摄氏度；Q10因子等于2。计算了酶的活化能、失活能和焓；NAD-焦磷酸化酶对NMN和ATP的表观Km值分别等于1.62×10⁻⁷ M和2.61×10⁻⁷ M。
