| + | == Publication Abstract from PubMed == | ||
| + | The bifunctional N(5) , N(10) methylenetetrahydrofolate dehydrogenase/cyclohydrolase (DHCH or FolD), widely distributed in prokaryotes and eukaryotes, is involved in biosynthesis of folate cofactors essential for growth and cellular development. The enzyme activities represent a potential antimicrobial drug target. We have characterized the kinetic properties of FolD from the Gram-negative pathogen Acinetobacter baumanni and determined high-resolution crystal structures of complexes with cofactor and two potent inhibitors. The data reveal new details with respect to the molecular basis of catalysis and potent inhibition. A major surprise was that our crystallographic data revealed a different structure for LY374571, an inhibitor studied as an antifolate, that was previously published. The implications of this observation are discussed. (c) 2012 The Authors Journal compilation (c) 2012 FEBS. | ||
