Inverting glycosyltransferase that catalyzes the transfer of one glucose moiety from UDP-glucose to an asparagine residue in peptides and proteins containing the NX(S/T) motif, resulting in their modification with a beta-linked 1,N-glucose. Likely acts as a key component of a general protein glycosylation system (Probable). L-asparaginyl-[protein] + UDP-alpha-D-glucose = H(+) + N(4)-(beta-D-glucosyl)-L-asparaginyl-[protein] + UDP Protein modification; protein glycosylation. Belongs to the glycosyltransferase 41 family.
