The biosynthetic enzymes involved in wall teichoic acid biogenesis in gram-positive bacteria have been the subject of renewed investigation in recent years with the benefit of modern tools of biochemistry and genetics. Nevertheless, there have been only limited investigations into the enzymes that glycosylate wall teichoic acid. Decades-old experiments in the model gram-positive bacterium, Bacillus subtilis 168, using phage-resistant mutants implicated tagE (also called gtaA and rodD) as the gene coding for the wall teichoic acid glycosyltransferase. This study and others have provided only indirect evidence to support a role for TagE in wall teichoic acid glycosylation. In this work, we showed that deletion of tagE resulted in the loss of α-glucose at the C-2 position of glycerol in the poly(glycerol phosphate) polymer backbone. We also reported the first kinetic characterization of pure, recombinant wall teichoic acid glycosyltransferase using clean synthetic substrates. We investigated the substrate specificity of TagE using a wide variety of acceptor substrates and found that the enzyme had a strong kinetic preference for the transfer of glucose from UDP-glucose to glycerol phosphate in polymeric form. Further, we showed that the enzyme recognized its polymeric (and repetitive) substrate with a sequential kinetic mechanism. This work provides direct evidence that TagE is the wall teichoic acid glycosyltransferase in B. subtilis 168 and provides a strong basis for further studies of the mechanism of wall teichoic acid glycosylation, a largely uncharted aspect of wall teichoic acid biogenesis. << Less

Insertional mutagenesis has revealed that a 22 kbp segment from the hisA region of the Bacillus subtilis 168 chromosome (310 degrees on the genetic map) contains at least six independent transcription units, all apparently devoted to production of cell envelope components. Genes concerned with synthesis of poly(glycerol phosphate), poly(groP), an essential cell wall polymer in B. subtilis 168, are organized in two divergently transcribed operons denoted tagABC and tagDEF. Nucleotide sequence analysis indicates that three of these six genes encode extremely basic polypeptides. The deduced products of the tagABC operon may be involved in poly(groP) assembly and export, whereas those of the tagDEF operon, which are very hydrophilic, are more likely to be implicated in poly(groP) precursor biosynthesis. The first gene of the tagDEF operon encodes glycerol-3-phosphate cytidylyltransferase (Pooley et al., 1991, Journal of General Microbiology 137, 921-928) and its deduced product has significant homology with cholinephosphate cytidylyltransferase from yeast. There is also substantial homology between the deduced products of tagB in the tagABC operon and tagF in the tagDEF operon. << Less
