Proteins from ETC complexes and the TCA cycle were experimentally determined from mouse and human heart mitochondria. The PTM information of the protein was retrieved from UniProt. The referenced phosphorylation sites were identified from their respective species but may have originated from different tissues other than the heart (e.g. mouse liver, human HeLa cells). Tissue-specific PTM distribution is a matter of intense investigation.
