===Crystal structure of penicillin binding protein 4 (dacB) from Escherichia coli, complexed with penicillin-G===

~~==Overview==~~

<!--

The ~~crystal structure of penicillin binding protein 4 (PBP4) from Escherichia coli~~, ~~which has both DD-endopeptidase and DD-carboxypeptidase activity~~, ~~is presented. PBP4 is one of 12 penicillin binding proteins in E. coli involved in~~ the ~~synthesis and maintenance of~~ the ~~cell wall~~. ~~The model contains a penicillin binding domain similar to known structures, but includes a large insertion which folds into domains with unique folds~~. ~~The structures of the protein covalently attached to five different antibiotics presented here show the active site residues are unmoved compared to the apoprotein~~, ~~but nearby surface loops and helices are displaced in some cases. The altered geometry of conserved active site residues compared with those of other PBPs suggests a possible cause for~~ the ~~slow deacylation rate of PBP4~~.

The line below this paragraph, {{ABSTRACT_PUBMED_16411754}}, adds the Publication Abstract to the page

(as it appears on PubMed at http://www.pubmed.gov), where 16411754 is the PubMed ID number.
