Publikováno v: Nature Structural & Molecular Biology. 15:1326-1333

Rotation of the central shaft gamma subunit in a molecular motor F(1)-ATPase is assumed to correlate with and probably be driven by domain motions of the three catalytic beta subunits. Here we observe directly these beta motions through an attached f

The chloroplast-type F(1) ATPase is the key enzyme of energy conversion in chloroplasts, and is regulated by the endogenous inhibitor epsilon, tightly bound ADP, the membrane potential and the redox state of the gamma subunit. In order to understand

Publikováno v: Journal of Biological Chemistry. 278:31848-31852

Chloroplast cyclophilin has been identified as a potential candidate of enzymes in chloroplasts that are regulated by thioredoxin (Motohashi, K., Kondoh, A., Stumpp, M. T., and Hisabori, T. (2001) Proc. Natl. Acad. Sci. U. S. A. 98, 11224–11229). I

Molecular evolution of the modulator of chloroplast ATP synthase: origin of the conformational change dependent regulation

Autor: Hiroki Konno, Toru Hisabori, Hanayo Ueoka-Nakanishi, Fumie Koyama

Publikováno v: FEBS Letters. 545:71-75

Chloroplast ATP synthase synthesizes ATP by utilizing a proton gradient as an energy supply, which is generated by photosynthetic electron transport. The activity of the chloroplast ATP synthase is regulated in several specific ways to avoid futile h
