Table 2. Stoichiometry of selected protein complexes from exponentially growing S. aureus cells were determined based on absolute protein quantification data obtained with the LC-IMSE approach.
| Protein complex | S. aureus | Reported stoichiometry | Referencea |
|---|---|---|---|
| SufB:SufC:SufD | 1:2:1 | 1:2:1b | 42 |
| AtpA:AtpD:AtpG:AtpH:AtpC | 6:5:1:1:1c | 3:3:1:1:1d | 57 |
| RpoB:RpoA | 1:2 | 1:2b | 58 |
| PdhA:PdhB:PdhC | 1:1:1 | 1:1:1 | 59 |
aReference for known stoichiometry.
bShown for E. coli.
cThe calculated molecule numbers lead to a different stoichiometry of the F1 complex as published because free subunits that are not integrated into the F1 complex may influence these values.
dShown for bovine mitochondria.
