Species
Bovine
Form
Lyophilized powder containing Tris, EDTA, and (NH4)2SO4
Enzyme Commission Number
EC 2.4.1.22
CAS No.
9031-68-9
Unit Definition
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)
Applications
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.
