Query: NC_009655:866281 Actinobacillus succinogenes 130Z chromosome, complete genome
Lineage: Actinobacillus succinogenes; Actinobacillus; Pasteurellaceae; Pasteurellales; Proteobacteria; Bacteria
General Information: Succinate-producing bacterium. Originally isolated from bovine rumen, this species is one of the most promising succinate producers known. It can utilize a variety of sugars and produce a very high volume of succinate, which is used by the pharmaceutical industry. This organism has been improved over time by growth on fermentable carbon and sodium monofluoroacetate and selection of fluoroacetate-resistant mutants which have a higher succinate yield. The succinate yield has also been improved via a metabolic engineering approach, by cloning and overproducing the PEP-carboxykinase gene which catalyzes the addition of carbon dioxide to PEP to form oxalacetate and can work physiologically in both directions
Subject: NC_010159:3033989 Yersinia pestis Angola, complete genome
Lineage: Yersinia pestis; Yersinia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This strain was isolated prior to 1985 and belongs to the antiqua biovar. It can ferment rhamnonse and melibiose which is a property usually associated with Yersinia pseudotuberculosis. Strain Angola belongs to a group of atypical Yersinia pestis strains with genotypic similarities that are intermediate between Y. pestis and Y. pseudotuberuclosis strains. Genotypic studies indicate that strain Angola is the oldest Y. pestis strain analyzed to date. It carries three plasmids that are similar to other Y. pestis plasmids but have aberrant sizes. The critical virulence factor, the V antigen, is different than that encoded by typical strains of Y. pestis and there is a deletion that affects the F1 operon. Strain Angola has been shown to be virulent by aerosol in mice.
