General Information

EC Number General Information Comment Organism
3.1.1.29 additional information enzyme structure and dynamics by NMR spectroscopy and molecular dynamics simulations. Of the substrate binding segments, the gate loop is rigid, the base loop displays slow motions, while the lid loop displays fast timescale motions. The NMR structure of Mycobacterium smegmatis MsPth shares the canonical Pth fold with theNMR structure of Mycobacterium tuberculosis MtPth Mycolicibacterium smegmatis
