Two structurally different monomeric and dimeric types of isocitrate dehydrogenase (IDH; EC isozymes were confirmed to exist in a psychrophilic bacterium, Colwellia psychrerythraea, by Western blot analysis and the genes encoding them were cloned and sequenced. Open reading frames of the genes (icd-M and icd-D) encoding the monomeric and dimeric IDHs of this bacterium, IDH-M and IDH-D, were 2,232 and 1,251 bp in length and corresponded to polypeptides composed of 743 and 416 amino acids, respectively. The deduced amino acid sequences of the IDH-M and IDH-D showed high homology with those of monomeric and dimeric IDHs from other bacteria, respectively. Although the two genes were located in tandem, icd-M then icd-D, on the chromosomal DNA, a Northern blot analysis and primer extension experiment revealed that they are transcribed independent of each other. The expression of the monomeric and dimeric IDH isozyme genes in C. maris, a psychrophilic bacterium of the same genus as C. psychrerythraea, is known to be induced by low temperature and acetate, respectively, but no such induction in the expression of the C. psychrerythraea icd-M and icd-D genes was detected. IDH-M and IDH-D overexpressed in Escherichia coli were p...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
