the enzyme catalyzes the assembly of lipid-transported N-acetylglucosaminyl-beta-1,4-N-acetylmuramoyl-L-Ala-gamma-D-Glu-meso-(diaminopimelic acid)-D-Ala-D-Ala units (lipid II) into linear peptidoglycan chains. These units are linked, at C1 of N-acetylmuramic acid, to a C55 undecaprenyl diphosphate. In an in vitro assay, lipid II functions both as a glycosyl donor and as a glycosyl acceptor substrate. Using substrate analogues, it is suggested that the specificity of the enzyme for the glycosyl donor substrate differs from that for the acceptor. The donor substrate requires the presence of both N-acetylglucosamine and MurNAc and a reactive group on C1 of the MurNAc and does not absolutely require the lipid chain which can be replaced by uridine. The enzyme appears to prefer an acceptor substrate containing a polyprenyl pyrophosphate on C1 of the MurNAc sugar

glycosyltransferase activity catalyzes glycan chain elongation from lipid II substrate undecaprenyl-pyrophosphoryl-N-acetylglucosamine-N-acetylmuramic acid-pentapeptide. PBP4 also catalyzes the aminolysis (D-Ala as acceptor) and hydrolysis of the thiolester donor substrate benzoyl-Gly-thioglycolate, indicating that PBP4 possesses both transpeptidase and carboxypeptidase activities

the enzyme is both an amidase and an endopeptidase. The enzyme is a lytic transglycosylase that degrades the glycan strands of the peptidoglycan into disaccharide units. The enzyme binds the cell wall, but only cleaves the glycan strands after the stem peptides have been removed. The enzyme alone is unable to cleave purified peptidoglycan but needs the presence of SpoIIP

malfunction
-
inhibition of the enzyme blocks peptidoglycan synthesis and leads to bacterial lysis and death
malfunction
an Staphylococcus aureus sgtB transposon mutant, with the monofunctional peptidoglycan glycosyltransferase SgtB inactivated, display a 4fold increase in the MIC of oxacillin, suggesting that alterations in the peptidoglycan structure can help bacteria compensate for the lack of lipoteichoic acid (LTA). Muropeptide analysis of peptidoglycans isolated from a wild-type strain and sgtB mutant strain does not reveal any sizable alterations in the peptidoglycan structure. In contrast, the peptidoglycan isolated from an LTA-negative ltaS mutant strain shows a significant reduction in the fraction of highly cross-linked peptidoglycan, which is partially rescued in the sgtB ltaS double mutant suppressor strain. Introduction of SgtB or MazE in the respective suppressor strain results in growth arrest. Increased resistance of the sgtB mutant to oxacillin. The increase in peptidoglycan cross-linking potentially strengthens the cell wall to better sustain the high internal turgor pressure and might be at least partly responsible for the observed growth improvement

the enzyme catalyze the polymerization of lipid II to form linear glycan chains, which, after cross linking by the transpeptidases, form the net-like peptidoglycan macromolecule, which encases bacteria and protects them from rupture under their high cytoplasmic pressure
physiological function
the enzyme is involved in synthesis of peptidoglycan, a key cell wall component in nearly all bacteria, protecting the cell from bursting by its internal turgor and maintaining cell shape. Peptidoglycan consists of glycan strands connected by short peptides and forms a continuous, mesh-like structure around the cytoplasmic membrane, called the sacculus. In Gram-negative species, such as Escherichia coli, the sacculus is made of a mainly single layer of peptidoglycan with a thickness of 3-6 nm. The glycan strands are made of alternating N-acetylglucosamine (GlcNAc) and N-acetylmuramic acid (MurNAc) residues linked by beta-1,4 glyosidic bonds. The peptides contain L- and D-amino acids and are linked to MurNAc residues. The sequence is L-Ala-D-iGlu-m-Dap-D-Ala-D-Ala (m-Dap, meso-diaminopimelic acid). During cell growth and division, the surface of the sacculus is enlarged by the incorporation of new peptidoglycan material. In this process, the precursor lipid II (undecaprenyl-diphosphoryl-MurNAc(pentapeptide)-GlcNAc) is polymerized by the glycosyltransferase reaction of the GTase domain of enzyme PBP1B

physiological function
Staphylococcus aureus has a typical Gram-positive cell envelope, which consists of a cytoplasmic membrane surrounded by a thick peptidoglycan layer. The peptidoglycan layer is a dynamic macromolecular structure that undergoes constant cycles of polymerization and hydrolysis to allow bacteria to grow and to divide. It is composed of glycan chains made of alternating N-acetylglucosamine and N-acetylmuramic acid residues connected by peptide bridges. This mesh-like sacculus is able to protect the cell from environmental threats while withstanding the high internal osmotic pressure. The final steps of peptidoglycan synthesis are catalyzed by enzymes termed penicillin binding proteins (PBPs) and coordinated actions of these enzymes are crucial for cell survival. PBPs with glycosyltransferase and transpeptidase activities polymerize the glycan chains and form peptide cross-bridges, while monofunctional transpeptidases, e.g. the monofunctional peptidoglycan glycosyltransferase SgtB in Staphylococcus aureus, have only the former activity. Important function of lipoteichoic acid (LTA) in cell wall integrity through its necessity for proper peptidoglycan assembly
physiological function
the majority of bacteria surround their cytoplasmic membrane with a peptidoglycan sacculus, a continuous layer that is required to maintain cell shape and osmotic stability. The basic chemical structure of peptidoglycan is well known, glycan strands consisting of alternating N -acetylglucosamine (GlcNAc) and N-acetylmuramic acid (MurNAc) residues connected by short stem peptides protruding from MurNAc. Peptides of neighboring glycan strands may be connected (i.e. cross-linked) forming a net-like layer. Peptide cross-links are formed by DD-transpeptidases. DD-transpeptidases covalently bind beta-lactam antibiotics such as penicillin, and are hence named penicillin-binding proteins (PBPs). Most bacteria possess several peptidoglycan synthases capable of catalyzing the glycosyltransferase (GTase) and/or transpeptidase (TPase) reactions. The Gram negative model organism Escherichia coli has three enzymes capable of performing both reactions, so-called bifunctional synthases: PBP1A, PBP1B, and PBP1C, two monofunctional transpeptidases, PBP2 and PBP3, and the monofunctional glycosyltransferase MtgA. The main peptidoglycan synthesis activity in the cell is provided by the semi-redundant PBP1A and PBP1B in consort with the transpeptidases PBP2 and PBP3, latter have essential roles in cell elongation and division, respectively. PBP1C and MtgA are dispensable for growth

ponA is synthesized with the addition of ribosome binding site (AGGAGGT) and linker (AAAACAT) upstream of the Met1 codon. This construct is inserted at the XbaI and HindIII sites of pACT3 (21), generating pMCC1, with PBP1a expression under control of the tac promoter. pMCC1 and pACT3 are transformed into hyperpermeable Escherichia coli isolate generating CBS-3546 and CBS-3567, respectively

introduction of wild-type and mutant SgtBs in a wild-type Staphylococcus aureus strain and in an ltaS mutant strain (ANG2135) deficient in lipoteichoic acid (LTA). Growth and cell morphology of wild-type and mutant strains. Introduction of SgtB or MazE in the respective suppressor strain results in growth arrest. Inactivation of MazE or SgtB is sufficient to allow Staphylococcus aureus to grow in the absence of LTA. Inactivation of SgtB leading to an increase in peptidoglycan cross-linking in an LTA-negative Staphylococcus aureus strain. Increased resistance of the sgtB mutant to oxacillin
