Introduction

Saves cells from dying since the appearance of life Outline: 1) Why is it important? Penicillin-binding proteins are essential for cell wall biogenesis. General info about bacterial cell wall biogenesis. Also, how bacteria mutate in order to avoid binding to beta-lactam. 2) Ligands, in particular phenoxyacetyl lactivicin. Also, how PBP binds lactivicin. Sample green scene: Penicillin-binding protein has four ligands, one of which is the electron-deficient olefin ligand or EDO

=Overall Structure

The secondary structures of PBP have certain affects on ligands TextToBeDisplayed Ligand has oxyanion hole to further binding potential. How does this help?


Binding Interactions

Additional Features

1)role in antibiotics and resistance the role of PBPsmetabolic pathways and enzymes are unique to bacteria in its synthesis is a very good target for drugs of selective toxicity

2)different PBPs and how they are classified into diverse categories found as both membrane-bound and cytoplasmic proteins

3)work as enzyme to catalyze synthesis of peptidoglycan


Quiz Question 1

Question related to PBP evolution and developing resistance to ß-lactams, likely related to active site mutations. Shows the conserved residues of Penicillin Binding Protein from most conserved to most variable.
