| Abstract: | PELDOR (Pulsed Electron eLectron DOuble Resonance) was applied to determinethe distance of between YZand QA
-inYD-less mutant of Chlamydomonas reinhardtiiin Tris-treatedand Zn-substituted preparation of photosystem II. The value of distance wasfound to be 34.5 ± 1 Â. A  2+1 electron spin echo method has beenapplied to measure the orientation of the radius-vector RfomYDto ChlZin a membrane-oriented photosystem II. The anglebetween Rand the membrane normal nwas determined to be 50 ±5°, using the distance 29.4 ± 0.5 Â determined in non-orientedPS II. |
