Phosphoglycosyl transferases (PGTs) initiate the biosynthesis of both essential and virulence-associated bacterial glycoconjugates including lipopolysaccharide, peptidoglycan and glycoproteins. PGTs catalyze the transfer of a phosphosugar moiety from a nucleoside diphosphate sugar to a polyprenol phosphate, to form a membrane-bound polyprenol diphosphosugar product. PGTs are integral membrane proteins, which include between 1 and 11 predicted transmembrane domains. Despite this variation, common motifs have been identified in PGT families through bioinformatics and mutagenesis studies. Bacterial PGTs represent important antibacterial and virulence targets due to their significant role in initiating the biosynthesis of key bacterial glycoconjugates. Considerable effort has gone into mechanistic and inhibition studies for this class of enzymes, both of which depend on reliable, high-throughput assays for easy quantification of activity. This review summarizes recent advances made in the characterization of this challenging but important class of enzymes.
