... incubated with the reactivase in the presence of ADP and Mg2+ and followed by nondenaturing PAGE, the bands of the enzyme and the reactivase were markedly reducedin density, and two bands of the enzymeÆreactivasecomplexes ... Positions of DD and its subun-its (aD, bD and cD) and the reactivase (DD-R) and its subunits (aR and bR) are indicated on the right of the gels. In (C), to improve visi-bility of the bands of ... that of the free enzyme and much shorter than that of the reactivas-e. When this peak was subjected to SDS⁄ PAGE, the peak comprised all of the subunits from the enzyme(a, b, and c) and the...
