Protein extraction: harvested cells are suspended in a buffer containing 50 mM Hepes-NaOH, pH 7,5, 30 mM CaCl2, 800 mM sorbitol, 1 mM ε-amino-n-caproic acid, and the cells are broken by vortexing 6×1 min at 4°C in the presence of glass beads, Protein samples are solubilized in Laemmli buffer containing 6 M urea and separated on a gel in presence of 6M urea
NdbA(thylakoid localization type 2 NAD(P)H dehydrogenase) is localized to the thylakoid membrane and is expressed at a low level in the wild type under photoautotrophic conditions. NdbA is heavily induced under photoactivated heterotrophic growth conditions.
