AtpG | ATPsynthase subunit II b' (chloroplastic)

KLH-conjugated mix of synthetic peptide derived from Arabidopsis thaliana AtpG Q0WMW8, At4g32260 and Chlamydomonas reinhardtii ATP synthase subunit b' A8J785

22.4 kDa (Chlamydomonas reinhardtii) 15.9 kDa (Arabidopsis thaliana)

Algae, Oryza sativa, Sorghum bicolor,  Zea mays, Volvox carteri

Application example

10 ug of chlorophyll/well of Chlamydomonas reinhardtii total cell extract (1), Chlamydomonas reinhardtii subunit II deletion mutant thylakoid membrane fraction (2), Arabidospsis thaliana thylakoid membrane fraction (3), 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 gamma antibody (AS09 457, 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 reagent, exposure time was 1 min.

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

Antibody reactivity for Arabidopsis thaliana has been confirmed on membrane fraction.

ATP synthase produces ATP from ADP in the presence of a proton gradient across the membrane. F-type ATPases have two components, CF(1) - the catalytic core - and CF(0) - the membrane proton channel. CF(1) has five subunits: alpha(3), beta(3), gamma(1), delta(1), epsilon(1). CF(0) has three main subunits: a, b and c.
