    l-talarate/galactarate dehydratase (TalrD/GalrD). On the basis of the different active site structures and different regiochemistries, we recognize that these functions represent an example of apparent, not actual, convergent evolution of function. The structure of GalrD-II and its active site architecture allow identification of the seventh functionally and structurally characterized subgroup in the enolase superfamily

  • Evolution of Enzymatic Activities in the Enolase Superfamily:  Characterization of the (<i>D</i>)-Glucarate/Galactarate Catabolic Pathway in <i>Escherichia coli</i>
    作者:Brian K. Hubbard、Marjan Koch、David R. J. Palmer、Patricia C. Babbitt、John A. Gerlt
    DOI:10.1021/bi981124f
    日期:1998.10.1
    The genes encoding the enzymes in the (D)-glucarate/galactarate catabolic pathway have been identified in the Escherichia coli genome. These encode, in three transcriptional units, (D)-glucarate dehydratase (GlucD), galactarate dehydratase, 5-keto-4-deoxy-(D)-glucarate aldolase, tartronate semialdehyde reductase, a glycerate kinase that generates 2-phosphoglycerate as product, and two hexaric acid transporters. We also have identified a gene proximal to that encoding GlucD that encodes a protein that is 72% identical in primary sequence to GlucD (GlucD-related protein or GlucDRP). However, whereas GlucD catalyzes the efficient dehydration of both (D)-glucarate and (L)-idarate as well as their epimerization, GlucDRP is significantly impaired in both reactions. Perhaps GlucDRP is an example of gene duplication and evolution in progress in the E. coli chromosome.
