Abstract
The present paper deals with the coordination of energy metabolism, glucose consumption rate, glycolytic and TCA cycle enzyme activities in the lysine-producing bacterium Brevibacterium flavum. It is shown, that inhibition of the elctron transport chain causes changes of the following sequence:
-
at first, TCA cycle enzymes are activated;
-
secondly, TCA cycle enzyme activity decreases, and glycolytic enzyme activities as well as glucose transport rate increase; there is a slight increase in Qo2 and a considerable one of O2 consumption in cyanide-resistant respiration pathway;
-
thirdly, TCA cycle enzyme activities and glucose transport rate decrease.
It is supposed, that coordination of carbon and energy metabolism in B. flavum depends on intracellular ATP concentration or energy charge value.
