Direct determinations of the concentration of semiquinone spin in redox equilibrium with the cytochrome b2 moiety were carried out at room temperature, in the presence of added pyruvate or in its absence. Results show that redox potentials of the one-electron couples of the prosthetic flavin are markedly affected by binding of pyruvate, the reaction product in the oxidation of L-lactate. The proportion of flavin semiquinone nearly reaches then 100 per cent.
在室温下，于添加丙酮酸或未添加丙酮酸的情况下，对与细胞色素b2部分处于氧化还原平衡的半醌自旋浓度进行了直接测定。结果表明，辅基黄素单电子对的氧化还原电位受到丙酮酸（L-乳酸氧化反应的产物）结合的显著影响。此时黄素半醌的比例几乎达到100%。
