Functional study of domains of class B penicillin-binding proteins 4b and SpoVD in Bacillus subtilis
How are penicillin-binding proteins sorted in cells? A bacterial cell wall can be regarded as a brick building, in which the bricks and the cement hold the building together, provide structure for the building, protect its contents, and allow only certain substances to enter. Many antibiotics target proteins that function in cell wall morphogenesis (the process of building the brick wall in this
