This structure supersedes the now removed PDB entry 1j92. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 2Å Ligands: CA, NAG Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function LALBA_MOUSE 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. Evolutionary Conservation Check, as determined by ConSurfDB.
