A Ca(2+)-dependent GalNAc/Man-specific lectin (CSL) from Cyclina sinensis was isolated, and its stimulatory action was characterized in yeast. CSL showed a potent effect on the production of ethanol by Saccharomyces cerevisiae. In this work, the changes in the protein expression profiles of S. cerevisiae after 24h of incubation with CSL were analyzed using label-free quantitative proteomics. A total of 1410 proteins were identified, but only 117 proteins showed significant differences in normalized volume (p<0.05). Among the latter proteins, 24 proteins were up-regulated, and 93 were down-regulated. Analysis of the proteome revealed that CSL triggered changes in the concentrations of some enzymes, such as increased expression of hexokinase, glyceraldehyde 3-phosphate dehydrogenase and enolase and decreased expression of dihydrolipoamide dehydrogenase and aldehyde dehydrogenase. These results indicate that CSL can cause some changes in the metabolic pathway involved in ethanol synthesis in S. cerevisiae. These data may help us understand the stimulatory mechanism of lectin in the fermentation process.
