The Degradation of Histidine by Aerobacter Aerogenes* by Boris Magasanik
In the course of the studies presented in the preceding paper it was observed that Aerobacter aerogenes could grow on histidine as the sole source of carbon and nitrogen (1). The nature of the microbial enzymes responsible for the complete degradation of histidine was not known and appeared therefore to be an appropriate subject for investigation. After initiation of these studies, the results ...
متن کاملPathway of L-xylose and L-lyxose degradation in Aerobacter aerogenes.
Pen&e utilization in Aerobacter aerogenes has been shown from fermentation studies with Cl%beled pentoses (1, 2) and with cell extracts (3) to involve the conversion of the pentose to n-xylulose 5-phosphate, which is further metabolized via n-sedoheptulose 7-phosphate, n-fructose 6-phosphate, and intermediates of the Embden-Meyerhof pathway. Although Aerobacter aerogenes can grow on all eight o...
متن کاملBasis for the mutational acquisition of the ability of Aerobacter aerogenes to grow on L-mannose.
Growth of Aerobacter aerogenes PRL-R3 on the unnatural hexose l-mannose as a sole carbon source is dependent upon the selection of a mutant. Growth of the mutant on l-mannose did not require the synthesis of novel enzymes for the degradation of l-mannose, since enzymes of the l-rhamnose degradative pathway could serve this function. However, unlike most other apparent gain mutations that have b...
متن کاملEffect of growth rate on histidine catabolism and histidase synthesis in Aerobacter aerogenes.
A study was made of how the catabolism of a carbon and energy source is affected by the biosynthetic demands of growing bacterial cells. Cultures of Aerobacter aerogenes in l-histidine medium were grown in a chemostat at rates determined by the supply of either sulfate or a required amino acid, l-arginine. It was discovered that the rate at which these cells grow under a biosynthetic restrictio...
متن کاملThe 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...
