Redox titration of multiple protein phosphorylations in pea chloroplast thylakoids

Redox titrations were carried out on the protein kinase reactions of isolated pea chloroplast thylakoid membranes. Of the 13 phosphoproteins observed by autoradiography, all were found to titrate with the same midpoint potential of around + 40 mV. Eleven proteins, including LHCII, D1, D2, CP43, a 9 kDa and a 55 kDa protein, were phosphorylated under reducing conditions, with a midpoint potentia...

Redox titration of fluorescence yield of photosystem II.

The variable fluorescence yield of photosystem II is dependent on the redox state of the fluorescence quencher molecule or the primary electron acceptor of the system. We have carried out redox titrations of fluorescence yield of a photochemically active photosystem-II reaction-center particle and have measured the redox potential of the photosystem-II primary acceptor.During reductive titratio...

A Bovine Model of Respiratory Chlamydia psittaci Infection: Challenge Dose Titration

This study aimed to establish and evaluate a bovine respiratory model of experimentally induced acute C. psittaci infection. Calves are natural hosts and pathogenesis may resemble the situation in humans. Intrabronchial inoculation of C. psittaci strain DC15 was performed in calves aged 2-3 months via bronchoscope at four different challenge doses from 10(6) to 10(9) inclusion-forming units (if...
