Regulation of sucrose-6-phosphate hydrolase activity in Streptococcus mutans: characterization of the scrR gene.

Previous results have implicated an important role for the enzyme IIScr, the sucrose-specific permease, in the transport of sucrose by cariogenic Streptococcus mutans. The product of the scrB gene, sucrose-6-phosphate hydrolase (Suc-6PH), is required for the metabolism of phosphorylated sucrose. The results from the utilization of scrB::lacZ fusions in S. mutans GS-5 have suggested that sucrose...

Trehalose 6-phosphate: a signal of sucrose status.

T6P (trehalose 6-phosphate), the precursor of trehalose, has come out of obscurity over 10 years to be appreciated as an important regulator of plant metabolism and development, quite possibly linking the two. This information has been gained from analysis of mutant and transgenic plants, which show strong, diverse and strategically important phenotypes. Plant genes that encode the trehalose pa...

A Tale of Two Sugars: Trehalose 6-Phosphate and Sucrose.

Trehalose 6-phosphate (Tre6P), the intermediate of trehalose biosynthesis, is an essential signal metabolite in plants, linking growth and development to carbon status. The Suc-Tre6P nexus model postulates that Tre6P is both a signal and negative feedback regulator of Suc levels, forming part of a mechanism to maintain Suc levels within an optimal range and functionally comparable to the insuli...

The sucrose–trehalose 6-phosphate (Tre6P) nexus: specificity and mechanisms of sucrose signalling by Tre6P

Trehalose 6-phosphate (Tre6P), the intermediate of trehalose biosynthesis, has a profound influence on plant metabolism, growth, and development. It has been proposed that Tre6P acts as a signal of sugar availability and is possibly specific for sucrose status. Short-term sugar-feeding experiments were carried out with carbon-starved Arabidopsis thaliana seedlings grown in axenic shaking liquid...

Sucrose phosphate synthase and sucrose accumulation at low temperature.

The influence of growth temperature on the free sugar and sucrose phosphate synthase content and activity of spinach (Spinacia oleracea) leaf tissue was studied. When plants were grown at 25 degrees C for 3 weeks and then transferred to a constant 5 degrees C, sucrose, glucose, and fructose accumulated to high levels during a 14-d period. Predawn sugar levels increased from 14- to 20-fold over ...
