| Product Name | lactose synthase |
| Example Structure | ![]() |
| Synonyms | alpha-lactalbumin, beta-1,4-galactosyltransferase, beta-GalT, beta1,4-galactosyltransferase, beta1,4-galactosyltransferase-1, beta4Gal-T1, c-LacdiNAcS, Gal-T1, GalNAc(beta1-4)GlcNAc synthase, glactosyltransferase, uridine diphosphogalactose-glucose, GT, HP0826, lacdiNAc, LACS, lactose synthase, lactose synthetase, LALBA, LgtB, More, N-acetyllactosamine synthase, UDP-galactose-glucose galactosyltransferase, UDPgalactose-glucose galactosyltransferase, UGT72B1 |
| EC Number | 2.4.1.22 |
| CAS Registry Number | 9030/11/9 |
| Comments | The enzyme is a complex of two proteins, A and B. In the absence of the B protein (¦Á-lactalbumin), the enzyme catalyses the transfer of galactose from UDP-galactose to N-acetylglucosamine (EC 2.4.1.90 N-acetyllactosamine synthase). |
