Abstract excerpt
beta-1,4-galactosyltransferase 1 (beta4gal-T1, EC 2.4.1.38) transfers galactose from UDP-galactose to free N-acetyl-D-glucosamine or bound N-acetyl-D-glucosamine-R. Soluble beta4gal-T1, purified from human milk has been refractory to structural studies by X-ray or NMR. In a previous study (Malissard et al. 1996, Eur. J. Biochem. 239, 340-348) we produced in the yeast Saccaromyces cerevisiae an N-deglycosylated...
