Comments P.4469 right column top paragraph: "In comparison, Al-Shawi et al. (primary source) measured turnover numbers in wild type membranes of 82 sec^-1 for ATP synthesis in non-DCCD-treated membranes and 425 s^-1 for ATP hydrolysis." Primary source abstract: "Wild-type enzyme had a turnover number of 82 s^-1 at pH 7.5 and 30 degrees C."
