L-Arabinose metabolism in Rhizobium japonicum.
l-Arabinose was metabolized through an oxidative pathway by extracts of a strain of Rhizobium japonicum. The findings showed that l-arabinose is converted into 2-keto-3-deoxy-l-arabonate, which is cleaved into glycoaldehyde and pyruvate.
متن کاملStudies on myocardial metabolism of protein and amino acids by the use of C14-labelled substrates.
(1) In order to study the relationship between the energy metabolism via TCA cycle and amino acid metabolism as well as protein synthesis, C14-labelled substrates were used for tracer experiment . (2) Considerable C14O2 formation was noted from carbohydrates such as acetate-1-C14, pyruvate-1-C14, and pyruvate-3-C14, while a smaller amount of C14O2 was produced from amino acids such as glycine1-...
متن کاملAntigenic analysis of Rhizobium japonicum by immunodiffusion.
Immunodiffusion reactions were studied with seven strains of Rhizobium japonicum and three strains of the cowpea miscellany by using antisera against eight of the strains. Most strains yielded only weak precipitin bands when untreated cell suspensions were used as antigens in the diffusions. Ultrasonic disruption or heat treatment of the cells led to stronger bands, and immersion in boiling wat...
متن کاملThe Metabolism of Amino Acids
It was shown by Seth and Luck (1) that the intestinal absorption of glycine and alanine by rabbits was followed by pronounced aminoacidemia. Other amino acids when administered in similar amounts provoked smaller increases in the amino nitrogen content of the blood. Glutamic acid and aspartic acid were absorbed with but a slight aminoacidemia. The question then arose as to whether these strikin...
متن کاملOn the DNA Content of the Bacteroids of Rhizobium japonicum
DNA Content, Nodules, Bacteroids, Rhizobium, Soybean The DNA content of bacteroids from large nodules of soybean plants infected with Rhizobium japonicum strain 61 -A -101 was found to be 1.20 x 10~14 g per cell. Bacteroids from smaller nodules had slightly less DNA as did the stationary phase, free-living cells; both giving a value of 0.92 x 10-14 g per cell. In comparing these data with those...
