LITERATURE
catalytic domain of R228K-Gal-T1 and mouse recombinant alpha-lactalbumin are cocrystallized in the presence of UDP-galactose and MnCl2. Crystals are grown at room temperature by the hanging drop method. Crystal structure of R228K-Gal-T1 complexed with alpha-lactalbumin, UDP-galactose, and Mn2+, determined at 1.9 Å resolution shows that the Asp318 side chain exhibits a minor alternate conformation, compared to that in the wild type
