The Biosynthesis of Capsular Polysaccharide in Aerobacter aerogenes

The biosynthesis of capsular polysaccharide in Aerobacter aerogenes.

The structure of Aerobacter aerogenes capsular polysaccharide.

A capsular polysaccharide produced by Aerobacter aerogenes has been purified and shown to consist of galactose, mannose, and glucuronic acid in a molar ratio of 2: 1: 1, respectively. Partial acid hydrolysis liberated an aldobiouronic acid identified as 2-0-P-D-glucuronosyl-D-mannose. Analysis of capsular polysaccharide by Smith periodate degradation further indicated that all of the galactose ...

Biosynthesis in Aerobacter aerogenes

Two pathways for methionine methyl formation, one cobalamindependent and one cobalamin-independent, corresponding to those observed in Escherichia coli PA 15 have been found in Aerobacter aerogenes. An initial difficulty in showing the cobalamin-dependent pathway in cellfree extracts proved to be due to the presence of enzymes which caused the removal of adenosylmethionine, a cofactor required ...

The differentiation of Aerobacter aerogenes and Aerobacter cloacae.

Many attempts, based on biochemical properties, have been made to differentiate strains of the tribe Eschericheae-a biochemically heterogeneous collection of the Enterobacteriaceae-into genera. In the sixth edition of Bergey's Manual (Breed et al., 1948), these strains, if of animal origin, are classified into three genera: Escherichia, Aerobacter, and Klebsiella. The genus Aerobacter is subdiv...
