The mechanisms of substrates interaction with the active site of Mycobacterium tuberculosis tyrosyl-tRNA synthetase studied by molecular dynamics simulations
Abstract:To study the mechanisms of substrates interaction with the active site of Mycobacterium tuberculosis tyrosyl-tRNA synthetase (MtTyrRS). Methods. Complexes of MtTyrRS with tyrosine, ATP and tyrosyl adenylate were constructed by superposition of the MtTyrRS structure and crystallographic structures of bacterial TyrRS. All complexes of MtTyrRS with substrates were investigated by molecular dynamics (MD) simulations in solution. Results. It was shown the formation of network of hydrogen bonds between substrates an… Show more
IMB-T130 inhibits the growth of MDR-TB and XDR-TB by targeting MtTyrRS. Because of its low cytotoxicity against mammalian cells, IMB-T130 is a promising new agent against drug-resistant M. tuberculosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
