Long-chain alkyl ester of AMP acts as an antagonist of glucose-induced signal transduction that mediates activation of plasma membrane proton pump in Saccharomyces cerevisiae

Article Abstract:

Research has been conducted on the long-chain alkyl AMP esters. The cytotoxic growth inhibitory effect of these esters on yeast strain cells has been examined.

Ribosomal protein gene transcription in Saccharomyces cerevisiae shows a biphasic response to nutritional changes

Article Abstract:

A novel mutant selection system is used to isolate yeast mutants lacking glucose upshift regulation of rp-gene transcription. Impaired growth on glucose was observed for the mutants, especially for grd1, which was attributed to limited histidine yield. Following the addition of glucose, the grd mutants exhibited a normal transient increase of rp-gene transcription, but this only preceded a sharp decline in rp-mRNA levels. These indicate that two phases characterize the glucose upshift response of rp-gene transcription, namely, an initial phase which is independent of ability to grow, and a sustained phase which is dependent on growth potential.
