Characterization of oxidative phosphorylation enzymes in Euglena gracilis and its white mutant strain W(gm)ZOflL / Katarína Krnáčová ... [et al.]. -- The enzymes involved in Euglena oxidative phosphorylation (OXPHOS) were characterized in this study. We have demonstrated that Euglena gracilis strain Z and its stable bleached non-photosynthetic mutant strain W(gm)ZOflL both possess fully functional OXPHOS apparatus as well as pathways requiring terminal alternative oxidase(s) and alternative mitochondrial NADH-dehydrogenase(s). Light (or dark) and plastid (non) functionality seem to have little effect on oxygen consumption, the activities of the enzymes involved in OXPHOS and the action of respiration inhibitors in Euglena. This study also demonstrates biochemical properties of complex III (cytochrome c reductase) in Euglena. (C) 2015 Federation of European Biochemical Societies. Published by Elsevier B.V.
