| 特异性 | Interconversion of the α- and β-anomeric forms of D-galactose is catalysed by β-galactose mutarotase (GMR) (1). (1) α-D-Galactose ↔ β-D-Galactose. The β-D-Galactose is oxidised by NAD+ to D-galactonic acid in the presence of β-galactose dehydrogenase (GALDH) at pH 7.5 (2). (2) β-D-Galactose + NAD+ → D-galactonic acid + NADH + H+ | |
| 具体活动 | Galactose dehydrogenase: ~ 200 U/mL at pH 8.6 and 25°C | |
| 单位定义 | One Unit of galactose dehydrogenase is defined as the amount of enzyme required to produce one μmole of NADH from NAD+ per minute at pH 8.6, at 25°C. | |
