Crystallographic Structure Determination of Bacteriophage Endolysins

Bacteriophages produce endolysins that target and cleave the hosts peptidoglycan to release their progeny at the end of the infection cycle. These proteins can be used for the eradication of pathogenic bacteria, but also for their detection. Endolysins may contain a single catalytic domain or several domains, including a cell wall binding domain. To understand their function in detail and design mutated or chimeric molecules with novel properties, knowledge of their structures and detailed mechanisms is necessary. X-ray protein crystallography is an excellent method to obtain high-resolution structures of biological macromolecules, and here we describe the method and the folds of known endolysin domains.

Automated summary

Endolysins, produced by bacteriophages, can be used to eliminate pathogenic bacteria and detect them. Understanding their structures and mechanisms is essential for designing molecules with novel properties. X-ray protein crystallography is a powerful method for obtaining high-resolution structures of these biological macromolecules.
