Abstract

Streptococcal extracellular NAD-glycohydrolase (EC 3.2.2.5) exists in two distinct states with respect to the optimal reaction temperature. Bacteria produce the enzyme form with optimum activity at about 40 degress C. Probably due to oxygen action, the enzyme is converted to a form with optimum activity at 30 degrees C. Compounds of the type of cysteine restore the initial state. The conversions are accompanied by enzyme activity fluctuations.

摘要

链球菌细胞外NAD-糖水解酶（EC 3.2.2.5）在最佳反应温度方面存在两种不同状态。细菌产生的酶形式在约40摄氏度时具有最佳活性。可能由于氧气作用，该酶会转化为在30摄氏度时具有最佳活性的形式。半胱氨酸类化合物可使酶恢复初始状态。这些转化伴随着酶活性的波动。
