| lipopolysaccharide 3-alpha-galactosyltransferase M-CSA #568 | Lipo-polysaccharide galactosyl transferase (LGTC) is a retaining glycosyl transferase which catalyses the transfer of alpha-D-galactose to a terminal lactose during the synthesis of lipo-polysaccharides with retention of stereochemistry at the anomeric carbon. The enzyme held at the surface of the bacterial plasma membrane through electrostatic interaction between basic residues and phospho-lipids and interactions between hydrophobic regions. | Defined by 8 residues: HIS:A-78ASP:A-103ASP:A-105ASP:A-130ASP:A-188GLN:A-189HIS:A-244LYS:A-250 | EC: 2.4.1.44 (PDB Primary Data) |
