Moreover, trehalose metabolism plays a role in control of the glycolytic
flux as indicated by the finding that growth on rapidly fermentable sugars is prevented in a tps1 mutant which is deficient in the catalytic subunit of the trehalose- 6-P synthase complex.
The precise molecular mechanism has not yet been completely worked out although
there are strong indications that this control occurs at the level of the hexose phosphorylation step [10,11].
Another potential function of glycogen and trehalose is in the progression of the cell division. An initial indication of this implication was obtained with continuous cultures of yeast at low dilution rates which exhibited spontaneous cell cycle-related oscillations.
