I63. Triosephosphate Dehydrogenase of Bacterium Coli
THE Booth-Green wet-crushing mill for bacteria has been used previously to prepare a cell-free juice from Bacterium coli in which the components of enzyme systems may be studied. In the present paper a juice has been prepared containing the system which oxidizes 3-phosphoglyceraldehyde. For yeast it has recently been shown that the actual substrate is 1:3-diphosphoglyceraldehyde [Warburg & Chri...
متن کاملThe Comparative Enzymology of Triosephosphate Dehydrogenase.
The properties of crystalline rabbit muscle (1) and yeast (2) triosephosphate dehydrogenases have been studied extensively (3). Velick and Udenfriend (4) have compared some of the properties of the two enzymes. They reported that, although the two enzymes have similar molecular weights and similar amino acid distributions with only small variations, there are differences in the internal structu...
متن کاملLight dependent increase of triosephosphate dehydrogenase in pea leaves.
Data from 3 lines of investigation were presented indicating that chlorophyll is not necessary for the increase in the triphosphopyridine nucleotide-requiring triosephosphate dehydrogenase accompanying the illumination of etiolated pea plants. These include A) the kinetics of the development of chlorophyll and enzyme activity, B) the presence of enzyme activity in leaves grown in the dark on no...
متن کاملThe mechanism of triosephosphate dehydrogenase inactivation by reduced diphosphopyridine nucleotide.
We have shown in a previous communication (1) that the enzyme triosephosphate dehydrogenase is rapidly inactivated in the presence of reduced diphosphopyridine nucleotide at physiological concentrations, temperature, and pH. Good stoichiometry was shown for the amount of enzyme inactivation, DPNH-X1 formation, and disappearance of sulfhydryl groups. It was then of particular interest to determi...
متن کاملSwimming efficiency of bacterium Escherichia coli.
We use measurements of swimming bacteria in an optical trap to determine fundamental properties of bacterial propulsion. In particular, we directly measure the force required to hold the bacterium in the optical trap and determine the propulsion matrix, which relates the translational and angular velocity of the flagellum to the torques and forces propelling the bacterium. From the propulsion m...
