1.97.1.1	evolution	the enzyme belongs to the dimethylsulfoxide (DMSO) reductase family, and group 3 ClrA proteins subfamily that participates in a key step of the chlorine cycle. The Rhodoplanes roseus chlorate reductase has other substantial differences to previously characterized chlorate reductases	-, 764585	
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)	744933

1.97.1.1	physiological function	the reduction of chlorate is one alternative to derive energy in an anoxic environment. Perchlorate reductases are periplasmic heterodimers of PcrA and PcrB, carrying a Mo-bis (pyranopterin guanine dinucleotide) cofactor and iron-sulfur clusters. Electrons are transferred from a membrane-associated, proton pumping c cytochrome of the NapC/NrfH family to PcrA. PcrC, a soluble multiheme c cytochrome, is predicted to participate in electron transport reactions	-, 744044
