| 1.97.1.1 | gene cluster clrABDC, genetic organization, chlorate reductase is cotranscribed with cytochrome c, UniProt ID B3VLA9, and other downstream genes in the gene cluster for chlorate respiration of Ideonella dechloratans. In vivo production of a single polycistronic transcript covering eight open reading frames including clrABDC, cyc, mobB and arsR. Transcription levels of the cyc and clrA genes are compared to each other by the use of qRT-PCR in RNA preparations from cells grown under aerobic or chlorate reducing anaerobic conditions. The two genes show the same mRNA levels under both growth regimes, indicating that no transcription termination occurs between them. Higher transcription levels are observed at growth without external oxygen supply. Quantitative real-time RT-PCR expression analysis | Ideonella dechloratans |

General Information
| EC Number | General Information | Comment | Organism |
|---|---|---|---|
| 1.97.1.1 | additional information | the genes for the enzymes chlorate reductase (clrABDC) and chlorite dismutase, necessary for chlorate metabolism and probably acquired by lateral gene transfer, are located in a gene cluster that also includes other genes potentially important for chlorate metabolism. Among those are a gene for cytochrome c (cyc) whose gene product may serve as an electron carrier during chlorate reduction, a cofactor biosynthesis gene (mobB) and a predicted transcriptional regulator (arsR) | Ideonella dechloratans |
| 1.97.1.1 | physiological function | a soluble periplasmic c-type cytochrome from Ideonella dechloratans donates electrons to Clr in vitro | Ideonella dechloratans |
