Ribose utilization by Veillonella alcalescens.
The utilization of ribose by Veillonella alcalescens has been further investigated. Nonfermentation of ribose is not a result of a phosphorylation lesion since ribose-phosphorylating activity was measured in cell extracts. Resting cells accumulated ribose-5-phosphate and nucleotides when (14)C-ribose was provided; no other sugar phosphates were detectable. Resting cells that were shifted to gro...
متن کاملThe pentose phosphate pathway.
I received my basic training in enzymology as a graduate student in the laboratory of Professor T. R. Hogness at the University of Chicago from 1936 to 1939. Hogness had constructed a photoelectric spectrophotometer modeled after the one in Otto Warburg’s laboratory in Berlin-Dahlem. I was assigned a problem on succinic dehydrogenase from beef heart, using the Warburg manometric apparatus, and ...

متن کاملKinetic properties of phosphotransacetylase from Veillonella alcalescens.
The phosphotransacetylase of Veillonella alcalescens catalyzes a reversible reaction with Michaelis-Menten kinetics for all substrates. The rate of the reverse reaction (the synthesis of acetyl coenzyme A from acetyl phosphate) was 6.5 times greater than the rate of the forward reaction (the synthesis of acetyl phosphate from acetyl coenzyme A). The apparent K(m) values determined for the forwa...
متن کاملSuccinic Acid Degradation by Veillonella Alcalescens.
samples were thus obtained for subsequent anaerobic assay with P. cereviseae. Typical assay results are indicated in Fig. 2. There is a marked increase in P. cereviseae activity caused by incubation of C. sporogenes with folic acid as compared with the corresponding nonincubated system. This activity could not be attributed to endogenous cell activity, and was not due to the utilization of aryl...
