Penicillin-binding proteins (PBPs) are a group of proteins that are characterized by their affinity for and binding of penicillin. They are a normal constituent of many bacteria; the name just reflects the way by which the protein was discovered. All β-lactam antibiotics (except for tabtoxinine-β-lactam, which … Prikaži več There are a large number of PBPs, usually several in each organism, and they are found as both membrane-bound and cytoplasmic proteins. For example, Spratt (1977) reports that six different PBPs are routinely detected … Prikaži več PBPs bind to β-lactam antibiotics because they are similar in chemical structure to the modular pieces that form the peptidoglycan. When they bind to penicillin, the β-lactam amide bond is ruptured to form a covalent bond with the catalytic serine … Prikaži več PASTA domain Prikaži več PBPs are all involved in the final stages of the synthesis of peptidoglycan, which is the major component of bacterial cell walls. Bacterial cell wall synthesis is essential to growth, … Prikaži več • Penicillin core. • Filamentation (top right of electron micrograph) occurs in some bacteria when PBP3 is inhibited. Prikaži več SpletSystems, methods, compositions, and kits for full-length whole transcriptome analysis (WTA). The method allows for 5'-based, 3'- based, and internal-based gene expression profiling. Nucleic acid targets (e.g., mRNAs) may be initially barcoded on the 3' end with the first plurality of oligonucleotide barcodes and subsequently barcoded on the 5' end …

The intrinsic resistance to /S-lactam drugs is mediated in part by alterations in the affinity of essential PBPs for penicillin (table 3).13"15 PBP alterations are also involved in the intrinsic resistance of other gram-negative as well as gram-positive bacteria.16 Gonococci have three PBPs.
