Conclusions
34
This study allows ,for the first time, an overall comparison of mitochondrial protein abundances in fermentation and respiration
Differences between the two fermentative substrates (glucose and galactose) are highlighted
Galactose could be considered as a substrate displaying an intermediate metabolism between fermentation and respiration

300 mitochondrial proteins were identified as phosphorylated ≈ 30% mitochondrial proteins
289 phosphorylation sites were quantified of which 214 were new significant enlargement of the yeast mitochondrial phosphosites map
1/3 of the phosphorylation sites varies from the 3 culture conditions tested (glucose, galactose, lactate)
Specific regulation seems to occur in galactose (respiro-fermentative medium)

OXPHOS
31 OXPHOS proteins were reproducibly quantified in the 3 growth conditions and showed different abundances according to the condition
19 of these proteins were phosphorylated, displaying 37 phosphosites
important role of phosphorylation in the regulation of the respiratory chain
For most of them, proteins were more abundant and more phosphorylated in lactate medium (respiratory condition) except for 2 proteins

- SILAC: stable isotope labeling by amino acids in cell culture cells are grown in culture media lacking essential (auxotrophic) amino acid(s). These amino acids are then supplied in either their natural form or in a stable isotope form to cause in vivo incorporation of the labeled amino acid(s). The differentially labeled samples are mixed and digested with a protease (most often trypsin) to obtain samples that can be readily analyzed by the mass spectrometer.
- iTRAQ : isobaric tagging for relative and absolute quantification
The ITRAQ method is based on the covalent labeling of the N-terminus and side chain amines of peptides from protein digestions with tags of varying mass. There are currently two mainly used reagents: 4-plex and 8-plex,
