Peptidoglycan glycosyltransferase is an enzyme required for bacterial cell wall synthesis.
It catalyzes the formation of peptidoglycan from disaccharide subunits on the bacterial cell surface.

II. General Structure
Note that the structure of this enzyme is
composed completely of alpha helices with no beta sheets.

This enzyme is found on the surface of the cell membrane, which means that the
enzyme would be positively charged where it interacts with the
membrane (yellow and green areas). The catalytic site is
represented by the dark blue area of the map.

These side chains have been identified as key players in the
catalytic activity of the enzyme,though their exact roles are not yet fully understood.
The ligand for peptidoglycan glycosyltransferase is penicillin.
As of right now, no crystal structure of the ligand-bound enzyme complex is available.
