摘要

淀粉酶在30、37、40、50℃条件下的最佳pH为6.5。在pH为6.5时,淀粉酶的最适温度为25℃,活化能为7.3 kcal/mol。在45℃和50℃下测定酶的热稳定性。Km值在不同温度下测定,在10°C和50°C时最低,在20°C时最高。

Some kinetic properties of amylase from the intestine of the rabbitfish, Siganus canaliculatus (Park)

The optimum pH of the amylase was 6.5 at 30, 37, 40 and 50°C. At pH 6.5, the amylase had an optimum temperature of 25°C and activation energy (Ea) of 7.3 kcal/mol. The thermostability of the enzyme was determined at 45 and 50°C. The Km values were determined at various temperatures and found to be lowest at 10 and 50°C and highest at 20°C.
