Glycosyl transferases can be integral membrane proteins with numerous TMSs that in some cases have been shown to transport the growing polysaccharide chain as it is being elongated in a group translocation process.

4.D.1 - The Putative Vectorial Glycosyl Polymerization (VGP) Family
4.D.3 - The Glycan Glucosyl Transferase (OpgH) Family
