Pantothenate synthetase

spinqualitylabelsall models Pantothenate synthetase complex with pantoate, AMPPNP, sulfate, Mg+2 ion (green), ethanol and glycerol (PDB entry 1n2e) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D Function Pantothenate synthetase or pantoate-beta-alanine ligase (PS) catalyzes the ATP-dependent condensation of pantoate and β-alanine to form pantothenate. Relevance Pantothenate (vitamin B5) biosynthesis is essential for the virulence of Mycobacterium tuberculosis thus its blockage can be used as a potential drug target. Structural highlights PS active site is located at the C-terminal of the central parallel β sheet. In this structure the pantoate substrate electron density is well defined in one subunit while the nucleotide electron density is well defined in the other. Water molecules are shown as red spheres. Pantoate binding site (chain A). AMPPNP binding site (chain B).
