Attractive target for drug against coronavirus
The crystal structure of the enzyme Mpro was identified at a resolution of 1.75 Angstroms. An Angstrom is a unit of length equal to one ten-millionth of a millimetre. Mpro is a key enzyme in the coronavirus’ life cycle as it processes polyproteins that are translated…
Modified tuberculosis vaccine as a therapy for cancer of the bladder
