生物活性/药理作用

Galactosyltransferase catalyzes the transfer of galactosyl molecules in the synthesis of oligosaccharides.

应 用

Galactosyltransferase is the catalytic component of the lactose synthetase system; it synthesizes lactose slowly in the absence of the regulatory protein α-lactalbumin. Galactosyltransferase will also transfer galactose from UDP-galactose to N-acetylglucosamine. This preparation is useful in the determination of α-lactalbumin, UDP-galactose, and N-acetylglucosamine.

有效单位定义

One unit will transfer 1.0 μmole of  galactose from UDP-galactose to D-glucose per min at pH 8.4 at 30 °C in the presence of 0.2 mg α-lactalbumin per mL of reaction mixture. (without added α-lactalbumin the activity is zero)
