WebCSA inhibits the enzymatic activity of the MCR-1 protein by binding to key amino acids at the active center of the MCR-1 protein. ... scanning electron microscope, lethal and semi-lethal models of infection in mice were used to assess the ability of CSA to restore the susceptibility of polymyxyn to E. coli. The interaction between CSA and MCR-1 ... WebThe structure of a protein is closely associated with its function; thus, a large number of structural analyses of proteins were performed using techniques such as X-ray crystallography and NMR. Although these methods provide structural information, they often fail because of difficulties in crystallizing the proteins that are complexed with ...
