Among others, biotin activates acetylCoA carboxylase, a potentially rate-limiting enzyme in myelin synthesis. Objectives:
To measure the cellular response to biotin availability, we metabolically labelled all proteins using stable isotope labelling of amino acids in cell culture (SILAC)17. Using this set-up we determined the cellular response of biotin, proteome and acetylome in cells exposed to normal amounts of biotin against those exposed … See more We first determined the proteome expression changes associated with excess and depleted amounts of biotin using a quantitative SILAC strategy as previously described17. In this comparison, we … See more To support our observations that Hst4p may participate in mitochondrial deacetylation, we investigated the cell cycle and biotin-dependent localization of Hst4p by fluorescence microscopy. To this end, the … See more To establish whether biotin availability causes a regulatory effect on protein acetylation, a MS-based acetyl-peptide immunoprecipitation enrichment procedure was performed28. … See more Yeast expresses several NAD+-dependent sirtuin deacetylases with similarity to the mitochondrial confined SIRT3 in mammals31.
