    Protein Summary

    The gene TM1169 from Thermotoga maritima encodes 3-oxoacyl-(acyl carrier protein) fabG reductase EC:  The enzyme belongs to a superfamily of Rossmann-fold NAD(P)(+)-binding proteins COG4982.  This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. This enzyme participates in fatty acid biosynthesis and polyunsaturated fatty acid biosynthesis.  Dozens of  structures have been solved for this class of enzymes, e.g 3FDA from Rickettsia Prowazekii.  The amino acid sequence of this protein is highly identical (99%) to a short-chain dehydrogenase/reductase SDR PF00106 from Thermotoga petrophila.  It is possible that this enzyme has a rather broad substrate specificity.
