Catalytic Properties of Chloroplast F1 ATPase Modified at Catalytic or Jbc Form

Instructions and help about Catalytic Properties Of Chloroplast F1 ATPase Modified At Catalytic Or Jbc

RL: We are looking at the turning gamma subunits and the epsilon subunits, and there is the c-ring in the membrane. The F1 complex is outside of the membrane, while the F0 complex is embedded in the membrane. There is the stalk, including the delta and the b-subunits. The alpha subunits are shown in light pink, the beta subunits are magenta. In the middle, the central stalk is rotating. The b-subunit stabilizes the hexamer, which means that the hexamer can't rotate. We will now look at a rendering of known structural states, and the conformational changes that are happening. The beta subunits are seen as a ribbon diagram. The ADP and inorganic phosphate diffuse into the active site, and the ATP has just been released. And simultaneously, the conformational change occurs in the beta subunit. If we zoom in to the active site, we can see the molecular structure of the substrates and the chemical reaction. Here is ADP with its two phosphates. They are all held in place by a network of hydr
