If a host
lacks galactosyltransferase, however, the Bt toxin cant locate the intestines and the worm sustains no damage to its internal composition.
Platelet -
associated galactosyltransferase produces efficient galactosylation when uridine diphosphate — galactose is added, affording a potentially simple method for storing platelets in the cold.
Our results clearly showed that regardless of the carbohydrate content, marked decreases in the incorporation of labeled sugars into transferrin and the enzymatic activities
of galactosyltransferase and sialyltrans - ferase occurred in rats administered chronic ethanol.
Three enzymes were needed to synthesise SLex:
galactosyltransferase to combine a glucose and a galactose sugar ring; sialyltransferase, to attach the sialyl group; and then finally fucosyltransferase to add a fucose sugar ring.
