PubMed Abstract:
Pantothenate kinase (PanK) is the rate-limiting enzyme in Coenzyme A biosynthesis, catalyzing the ATP-dependent phosphorylation of pantothenate. We solved the co-crystal structures of PanKs from Staphylococcus aureus (SaPanK) and Klebsiella pneumonia (KpPanK) with N-[2-(1,3-benzodioxol-5-yl)ethyl] pantothenamide (N354-Pan). Two different N354-Pan conformers interact with polar/nonpolar mixed residues in SaPanK and aromatic residues in KpPanK. Additionally, phosphorylated N354-Pan is found at the closed active site of SaPanK but not at the open active site of KpPanK, suggesting an exchange of the phosphorylated product with a new N354-Pan only in KpPanK. Together, pantothenamides conformational flexibility and binding pocket are two key considerations for selective compound design.
