Webb12 jan. 2024 · Chloroplast genes encode ∼37 thylakoid membrane proteins such as the PSII reaction center protein D1 and D2, and the PSI subunits PsaA and PsaB, which are synthesized in the stroma and integrated into thylakoid membranes through a cotranslational process ( Zoschke and Barkan, 2015 ). WebbThe localisations of the fusion proteins expressed in transgenic wheat plants and under the control of the rice actin promoter were compared to an untargeted GFP control. GFP fluorescence was localised to non-green plastids in pollen, roots and seed endosperm and detected in isolated leaf chloroplasts using a GFP-specific antibody.

WebbBefore reaching their final destination, the lipids and proteins in the transport vesicles need to be sorted, packaged, and tagged so that they wind up in the right place. This sorting, tagging, packaging, and distribution takes place in the Golgi apparatus (Golgi body), an organelle made up of flattened discs of membrane. Webb12 mars 2024 · Here, we identified two Arabidopsis ankyrin-repeat proteins, STT1 and STT2, that specifically mediate sorting of chloroplast twin arginine translocation (cpTat) pathway proteins to thylakoid membranes. STT1 and STT2 form a unique hetero-dimer through interaction of their C-terminal ankyrin domains.
