SIALIDASE FROM SALMONELLA TYPHIMURIUM COMPLEXED WITH EPANA INHIBITOR
OverviewOverview
The structure of Salmonella typhimurium LT2 neuraminidase (STNA) is, reported here to a resolution of 1.6 angstroms together with the, structures of three complexes of STNA with different inhibitors. The first, is 2-deoxy-2,3-dehydro-N-acetyl-neuraminic acid (Neu5Ac2en or DANA), the, second and third are phosphonate derivatives of N-acetyl-neuraminic acid, (NANA) which have phosphonate groups at the C2 position equatorial (ePANA), and axial (aPANA) to the plane of the sugar ring. The complex structures, are at resolutions of 1.6 angstroms, 1.6 angstroms and 1.9 angstroms, respectively. These analyses show the STNA active site to be topologically, inflexible and the interactions to be dominated by the arginine triad, with the pyranose rings of the inhibitors undergoing distortion to ...
