Maltotriosyl transferase, process for production thereof, and use thereof
The object is to provide a novel glycosyltransferase and the use thereof, the glycosyltransferase catalyzes transglucosylation of maltotriose units under conditions which can be employed for the processing of foods or the like. Provided is a maltotriosyl transferase which acts on polysaccharides and oligosaccharides having α-1,4 glucoside bonds, and has activity for transferring maltotriose units to saccharides, the maltotriosyl transferase acting on maltotetraose as substrate to give a ratio between the maltoheptaose production rate and maltotriose production rate of 9:1 to 10:0 at any substrate concentration ranging from 0.67 to 70% (w/v)..

Group b streptococcus vaccine
This application relates to improved group b streptococcus (“gbs”) saccharide-based vaccines comprising combinations of gbs polysaccharides with polypeptide antigens, and vice versa, such that the polypeptide and the saccharide each contribute to the immunological response in a recipient. The combination is particularly advantageous where the saccharide and polypeptide are from different gbs serotypes.
