Analysis of an Erwinia chrysanthemi gene cluster involved in pectin degradation.
Condemine G., Robert-Baudouy J.
A group of four genes of Erwinia chrysanthemi involved in pectin degradation has been characterized. These four genes form independent transcription units and are regulated by the negative regulatory gene, kdgR. The functions of two of these genes are known: kduD codes for the 2-keto-3-deoxyglucon ... >> More
A group of four genes of Erwinia chrysanthemi involved in pectin degradation has been characterized. These four genes form independent transcription units and are regulated by the negative regulatory gene, kdgR. The functions of two of these genes are known: kduD codes for the 2-keto-3-deoxygluconate oxydoreductase and kdul for the 5-keto-4-deoxyuronate isomerase, two enzymes of the pectin degradation pathway. kdgC has 36% homology with pectate lyase genes of the periplasmic family but its product does not seem to have pectinolytic activity. The fourth gene, kdgF, could have a role in the pathogenicity of E. chrysanthemi. A comparison of the regulatory regions of all the genes controlled by kdgR allowed better definition of the KdgR-binding-site consensus. << Less

Escherichia coli kduD encodes an oxidoreductase that converts both sugar and steroid substrates.
Tubeleviciute A., Teese M.G., Jose J.
A previously unidentified oxidoreductase from Escherichia coli catalyzes the regioselective reduction of eukaryotic steroid hormone 11-deoxycorticosterone (11-DOC) to the valuable bioactive product 4-pregnen-20,21-diol-3-one.

A previously unidentified oxidoreductase from Escherichia coli catalyzes the regioselective reduction of eukaryotic steroid hormone 11-deoxycorticosterone (11-DOC) to the valuable bioactive product 4-pregnen-20,21-diol-3-one. In nature, a reduction of C-20 carbonyl of C21 steroids is catalyzed by diverse NAD(P)H-dependent oxidoreductases. Enzymes that possess 20-ketosteroid reductase activity, however, have never before been described in E. coli. Our present study aimed to identify and characterize the E. coli enzyme which possesses 20-ketosteroid reductase activity against eukaryotic steroid hormone 11-DOC. We partially purified the enzyme from E. coli DH5α using protein chromatography techniques. Mass spectrometry revealed the presence of three NADH-specific oxidoreductases in the sample. The genes encoding these oxidoreductases were cloned and overexpressed in E. coli UT5600 (DE3). Only the overexpression of 2-dehydro-3-deoxy-D-gluconate 5-dehydrogenase (KduD) encoded by kduD gene enabled the whole-cell biotransformation of 11-DOC. A 6xHis-tagged version of KduD was purified to homogeneity and found to reduce several eukaryotic steroid hormones and catalyze the conversion of novel sugar substrates. KduD from E. coli is therefore a promiscuous enzyme that has a predicted role in sugar conversion in vivo but can be used for the production of valuable bioactive 20-hydroxysteroids. << Less
