Showing metabocard for Alpha-Lactose (BMDB0000186)

General function:

Involved in alpha-tubulin binding

Specific function:

The Golgi complex form catalyzes the production of lactose in the lactating mammary gland and could also be responsible for the synthesis of complex-type N-linked oligosaccharides in many glycoproteins as well as the carbohydrate moieties of glycolipids.

Gene Name:

B4GALT1

Uniprot ID:

P08037

Molecular weight:

44843.0

Reactions

General function:

Involved in calcium ion binding

Specific 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.

Gene Name:

LALBA

Uniprot ID:

P00711

Molecular weight:

16247.0

Reactions

General function:

Carbohydrate transport and metabolism

Specific function:

Lectin that binds to various sugars: mannose = ManNAc > fucose > GlcNAc > glucose = maltose > galactose > lactose > GalNAc. Could play a role in immune defense.
