10 ug of chlorophyll/well of Chlamydomonas reinhardtii total cell extract (1), Chlamydomonas reinhardtii subunit gamma deletion mutant thylakoid membrane fraction (2), Arabidospsis thaliana thylakoid membrane fraction (3), Chlamydomonas reinhardtii thylakoid membrane preparation (4) were separated on 12-18% acrylamide-8M urea gel and blotted to nitrocellulose membrane. Filters were blocked 1 h with 5% dry milk in 1 x PBS and probed with anti-ATP synthase subunit c antibody (AS09 591, 1: 10 000, 1h) and secondary HRP-conjugated anti-rabbit antibody (1: 10 000, 1 h) in 1 x PBS containing 5% dry milk. All steps were performed at RT with agitation. Signal was detected with chemiluminescent detection, exposure time 30’’.
Arabidopsis membrane preparation has been done according to Lezhneva et al. (2008) A novel pathway of cytochrome c biogenesis is involved in the assembly of the cytochrome b6f complex in arabidopsis chloroplasts. J Biol. Chem., 283:24608-24616 and Chlamydomonas membranes were prepared according to Chua & Bennoun (1975) Thylakoid membrane polypeptides of Chlamydomonas reinhardtii: wild-type and mutant strains deficient in photosystem II reaction center. PNAS 72:2175-2179

F-type ATPase (ATP synthase) is the universal enzyme that synthesizes ATP from ADP and phosphate using the energy stored in a transmembrane ion gradient. Multiple copies of the c subunit build up the ring structure (in spinach a 14-mer of ~112 kDa) of the membrane bound Fo-part of the enzyme.
