Work in the Dessen lab on Penicillin-Binding Proteins and cell wall elongation complexes is supported by grants from the Agence Nationale de la Recherche (ANR-18-CE11-0019), FAPESP (São Paulo Research Foundation) grant 2017/12,436-9, and the Laboratoire Intenational Associé (LIA) BACWALL (CNRS). The penicillin-binding proteins are essential enzyme catalysts for the biosynthesis of the cell wall, and understanding how this cell wall is integrated into the protective cell envelope of the PCR was used to identify penicillin resistance in 1,062 clinical isolates of Streptococcus pneumoniae. Three sets of primers were designed to amplify (i) a 240-bp fragment of the penicillin-binding protein (PBP) 2B gene (pbp2b) of penicillin-susceptible S. pneumoniae (PSSP), (ii) a 215-bp fragment of the class A mutations of the pbp2b gene present in penicillin-resistant S. pneumoniae, and Venatorx Pharmaceuticals is developing a novel class of non-beta-lactam molecules that kill bacteria by the same selective mechanism as beta-lactams — blocking cell wall synthesis via binding to the bacterial penicillin binding proteins (PBPs). Chemically distinct from the beta-lactams, these new molecules have been designed to be impervious to degradation by any beta-lactamases. Penicillin-binding proteins (PBPs) catalyze the final stages of peptidoglycan synthesis. Although PBPs are biochemically and physiologically well characterized, their broader effects, especially their effects on organismal fitness, are not well understood.

They are a normal constituent of Staphylococcus aureus penicillin-binding protein PBP2 is an enzyme involved in the last stages of peptidoglycan assembly and is an important player in the mechanism of methicillin resistance of this pathogen. PBP2 localized to the division site but its recruitment to the forming division septum was prevented after acylation by oxacillin. Penicillin‐binding protein 7 (PBP7) and its proteolytic degradation product PBP8 are shown to be soluble proteins, which can be set free from whole cells of Escherichia coli by an osmotic shock. The proteins are loosely associated with the membranes and are totally released into the supernatant in the presence of 1 M NaCl.
