  • Title: Thioredoxin target proteins in chloroplast thylakoid membranes.
    Author: Balmer Y, Vensel WH, Hurkman WJ, Buchanan BB.
    Journal: Antioxid Redox Signal; 2006; 8(9-10):1829-34. PubMed ID: 16987035.
    Abstract:
    In recent years, impressive progress has been made in the identification of thioredoxin-linked proteins. However, due to technical difficulties inherent in working with hydrophobic proteins, identifications so far have been restricted to proteins in the soluble fraction. Thus, our knowledge of redox regulated membrane proteins is quite limited. To gain information in this area, the authors have applied an adaptation of the approach based on the fluorescent thiol probe monobromobimane (mBBr) to identify redox-linked proteins of chloroplast thylakoids. By application of this procedure, 14 potential membrane-bound thioredoxin target proteins were identified, including seven new candidates functional in processes associated with photosynthetic electron flow, ATP synthesis, and Photosystem II/Photosystem I state transitions.
