Chains	Enzyme Name	Description	Catalytic Residues
A	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.
