In this review, we present a summary of how computer modeling has been used in the development of covalent modifier drugs. Covalent modifier drugs bind by forming a chemical bond with their target. This covalent binding can improve the selectivity of the drug for...

Without exception, modern hypotheses explaining the origin of eukaryotes assume evolution from two (or more) distinct prokaryotes. Almost all prokaryotic cell membranes possess a chemiosmosis system, whereas eukaryotic cell membranes have lost that ability. Nevertheless,...
