BIOPEP-UWM: Report
| ID | 1115 |
| Name | alpha-lactalbumin, gen. var. B, precursor, bovine (Bos taurus) |
| sequence |
| Function: | |
| Regulatory subunit of lactose synthase, changes the substrate specificity of galactosyltransferase in the mammary gland making glucose a good acceptor substrate for this enzyme. This enables LS to synthesize lactose, the major carbohydrate component of milk. In other tissues, galactosyltransferase transfers galactose onto the N-acetylglucosamine of the oligosaccharide chains in glycoproteins. Ref.: Swiss-Prot database (www.expasy.org). | |

| Additional information: |
| Protein known as: lactose synthase B protein, allergen Bos d 4. Chain: from 20 to 142; signal peptide: from 1 to 19. Alpha-lactalbumin is synthesized only in the mammary gland. This protein is a regulatory subunit of lactose synthase and changes substrate specificity of galactosyltransferase in the mammary gland making glucose a good acceptor substrate for this enzyme.
