ENZYME entry: EC 2.4.1.22
Accepted Name |
lactose synthase.
|
Alternative Name(s) |
N-acetyllactosamine synthase. |
UDP-galactose--glucose galactosyltransferase. |
Reaction catalysed |
D-glucose + UDP-alpha-D-galactose <=> H(+) + lactose + UDP |
Comment(s) |
- The enzyme is a complex of 2 proteins A and B.
- In the absence of the B protein (alpha-lactalbumin) the enzyme
catalyzes the transfer of galactose from UDP-galactose to
N-acetylglucosamine (cf. EC 2.4.1.90).
