Abstract
Tentoxin at 10--1000 micrometer causes a marked species-selective stimulation of coupling factor 1 Ca2+-dependent ATPase activity (Ka 6.3 . 10(3) M-1). This effect decreases the Km for ATP to about 0.3 mM and increases V 2.75-fold. Above 1.6 micrometer tentoxin the rate of coupled electron transport was reduced to basal without uncoupling.
摘要
浓度为10 - 1000微摩尔的抗霉素A能显著地选择性刺激偶联因子1的Ca2+依赖性ATP酶活性（Ka为6.3×10³M⁻¹）。这种作用使ATP的米氏常数降至约0.3毫摩尔，并使V增大2.75倍。当抗霉素A浓度高于1.6微摩尔时，偶联电子传递速率降至基线水平但未发生解偶联。
