'''X-RAY STRUCTURE OF ESCHERICHIA COLI ENOYL REDUCTASE WITH BOUND NAD AND THIENO-DIAZABORINE'''<br />


==Overview==
==X-RAY STRUCTURE OF ESCHERICHIA COLI ENOYL REDUCTASE WITH BOUND NAD AND THIENO-DIAZABORINE==
Enoyl reductase (ENR), an enzyme involved in fatty acid biosynthesis, is the target for antibacterial diazaborines and the front-line antituberculosis drug isoniazid. Analysis of the structures of complexes of Escherichia coli ENR with nicotinamide adenine dinucleotide and either thienodiazaborine or benzodiazaborine revealed the formation of a covalent bond between the 2' hydroxyl of the nicotinamide ribose and a boron atom in the drugs to generate a tight, noncovalently bound bisubstrate analog. This analysis has implications for the structure-based design of inhibitors of ENR, and similarities to other oxidoreductases suggest that mimicking this molecular linkage may have generic applications in other areas of medicinal chemistry.
