Abstract

The electron paramagnetic resonance method was used to study the interactions of amaranthin with isolated class B chloroplasts from broad bean (Vicia faba L.) and amaranth (Amaranthus tricolor L.) during the light-driven electron and proton transport. Amaranthin was shown to interact with electron transport chain of chloroplasts at the PS II level; it also affects the electron transport near PS I. At the same time, amaranthin had no significant inhibitory effect on the light-dependent formation of the transmembrane pH gradient.
