✦ Synopsis
The inactivation of fructose-l,6-bisphosphatase, isocitrate lyase and cytoplasmic malate dehydrogenase in Candida maltosa was found to occur after the addition of glucose to starved cells. The concentration of cyclic AMP and fructose-2,6-bisphosphate increased drastically within 30 s when glucose was added to the intact cells of this yeast. From these results it was concluded that catabolite inactivation, with participation of cyclic AMP and fructose-2,6bisphosphate, is an important control mechanism of the gluconeogenetic sequence in the n-alkane-assimilating yeast Candida maltosa, as described for Saccharomyces cerevisiae.
