The binding pockets on proteins are mobile and dynamic and constantly changing shape. Some pockets or subpockets can be described as transient because they are not always present in the given protein. In structure-based drug design procedures, the dynamic nature of the target protein is usually neglected. A crystal structure of the protein may not reveal transient pockets as it provides a picture of a fixed state of the protein. The analysis of molecular dynamics simulations of a protein can however reveal them. Transient pockets are particularly interesting because they can open and close, allowing ligands to bind. Transient pockets can therefore be exploited to design compounds with greater target specificity or better kinetic binding properties than would be achieved by considering the target as a static structure.<\/p>\n\n\n\n<div class=\"wp-block-image dt-single-image\"><figure class=\"alignright\"><a class=\"dt-single-image\" href=\"http:\/\/www.h-its.org\/wp-content\/uploads\/2017\/05\/Picture1-2.png\"><img decoding=\"async\" src=\"http:\/\/www.h-its.org\/wp-content\/uploads\/2017\/05\/Picture1-2-273x300.png\" alt=\"picture1\" class=\"wp-image-15591\" \/><\/a><figcaption>An example of the application of TRAPP to aid drug discovery for neglected tropical diseases caused by trypanosomatid parasites.
