Show all pathways known for 1.97.1.12Display the word mapDisplay the reaction diagram Show all sequences 1.97.1.12? 21000-22000 Da, photosystem 1 subunit PsaF that is involved in the docking of the electron-donor proteins plastocyanin and cytochrome c6, SDS-PAGE 713465
Show all pathways known for 1.97.1.12Display the word mapDisplay the reaction diagram Show all sequences 1.97.1.12dimer in strain TS-821 PSI forms tetrameric, dimeric, and monomeric species, a tetrameric PSI has two PSI dimers associated together with interdimer gaps, while the PSI dimer is composed of two tightly tethered PSI monomers, subunit organization, structure comparisons, overview 746026
Show all pathways known for 1.97.1.12Display the word mapDisplay the reaction diagram Show all sequences 1.97.1.12heterotetramer two-dimensional maps obtained by single particle electron microscopy clearly show that the tetramer lacks four-fold symmetry and is actually composed of a dimer of dimers with C2 symmetry, cryo-electron microscopy is used for 3D reconstruction of the PSI tetramer complex and a 3D model at 11.5 A resolution is obtained. A 2D map within the membrane plane of about 6.1 A is used for modeling, structure model comparison with the PSI structure of Thermosynechococcus elongatus at 2.5 A, PDB ID 1JB0, overview. The PsaL subunit of strain TS-821 is modeled using PsaL subunit of Pisum sativum as a template, PDB ID 4Y28L. The modeled PsaL subunit of TS-821 is used to substitute the existing PsaL subunit in crystal structure of Thermosynechococcus elongatus and most of the subunits from the crystal structure of Thermosynechococcus elongatus are fitted separately into the 3D volumemap of TS-821. Comparison of trimeric interface of Thermosynechococcus elongatus with interface type 1 of TS-821 744411

Show all pathways known for 1.97.1.12Display the word mapDisplay the reaction diagram Show all sequences 1.97.1.12More plant and algal PSI complexes contain 14-15 protein subunits. Of these, only PsaA, PsaB, and PsaC bind the cofactors of the electron transfer system. PsaA and PsaB form the core complex around which other subunits are organized. The PsaC, PsaD, PsaH, and PsaE proteins form the stromal peripheral domain that contains the terminal electron donors and the ferredoxin-docking site. PsaN of plant and algal PSI is a lumenal peripheral protein. PsaN and the large lumenal domain of PsaF form the plastocyanin docking site of plant and algal PSI. The remaining proteins of PSI are integral membrane proteins with 1–3 transmembrane helices. The function of the PSI proteins 710876
