Escherichia coli - Enzymology
Research News and Information
Definition of 'Escherichia coli'A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc. |

Biotin synthase (BioB) is an iron-sulfur enzyme that catalyzes the last step in biotin biosynthesis, the insertion of sulfur between the C6 and C9 atoms of dethiobiotin to complete the thiophane ring of biotin. Recent in vitro experiments suggest ... Read more...
Modular coenzyme specificity: a domain-swopped chimera of glutamate dehydrogenase.
30 Oct 2009 Domain-swopped chimeras of the glutamate dehydrogenases from Clostridium symbiosum (CsGDH) (NAD(+)-specific) and Escherichia coli (EcGDH) (NADP(+)-specific) have been produced, with the aim of testing the localization of determinants of coenzyme ... Read more...
An oxygen-sensing diguanylate cyclase and phosphodiesterase couple for c-di-GMP control.
18 Oct 2009 A commonly observed coupling of sensory domains to GGDEF-class diguanylate cyclases and EAL-class phosphodiesterases has long suggested that c-di-GMP synthesizing and degrading enzymes sense environmental signals. Nevertheless, relatively few signal ... Read more...
