Proteins used by the predatory yeast Saccharomycopsis schoenii as it attacks and kills the prey cell Saccharomyces cerevisiae

Saccahromycopsis schoenii belongs to a genus of yeasts that have the ability to attack and kill other yeast and fungi. De novo genomic sequencing and genome assembly suggests that S. schoenii might belong to the CTG clade. To examine whether it translated CTG codons to leucine (standard codon usage) or serine (alternative codon usage), we analysed its proteome during growth on full media. To see if translation is changed during nutritional stress or during predation on a prey cell (Saccharomyces cerevisiae), we analysed and quantified its proteome during these conditions compared to its proteomic expression in full media.
