Table 2. Contributions of the L/M residue pairs that are responsible for Em(HL)>Em(HM) (more than 10 mV) in the dark-state structure (mV).
Difference: [contribution of subunit L to Em(HL)] + [contribution of subunit M to Em(HL)] – [contribution of subunit L to Em(HM)] – [contribution of subunit M to Em(HM)].
