Evolution of enzymatic activities in the enolase superfamily: characterization of the (D)-glucarate/galactarate catabolic pathway in Escherichia coli.
Hubbard B.K., Koch M., Palmer D.R., Babbitt P.C., Gerlt J.A.
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 semiald ... >> More
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. << Less

Rhombohedral crystals of 2-dehydro-3-deoxygalactarate aldolase from Escherichia coli.
Blackwell N.C., Cullis P.M., Cooper R.A., Izard T.
2-Dehydro-3-deoxygalactarate (DDG) aldolase (E.C. 4.1.2.20) catalyzes the reversible aldol cleavage of DDG and 2-dehydro-3-deoxyglucarate to pyruvate and tartronic semialdehyde.

2-Dehydro-3-deoxygalactarate (DDG) aldolase (E.C. 4.1.2.20) catalyzes the reversible aldol cleavage of DDG and 2-dehydro-3-deoxyglucarate to pyruvate and tartronic semialdehyde. Rhombohedral crystals of recombinant DDG aldolase from Escherichia coli K-12 were obtained. The crystals belong to space group R32 with unit-cell parameters a = 93 A, alpha = 85 degrees. The crystals diffract to beyond 1.8 A resolution on a Cu Kalpha rotating-anode generator. The asymmetric unit is likely to contain two molecules, corresponding to a packing density of 1.34 A3 Da-1. << Less
