WebAug 5, 2024 · The ABI3p:OXA2a plants displayed growth retardation due to a reduction in the steady-state abundances of both c-type cytochromes, cytochrome c 1 and cytochrome c. The observed reduction in the steady-state abundance of complex III could be attributed to cytochrome c 1 being one of its subunits. Cytochromes are redox-active proteins containing a heme, with a central iron (Fe) atom at its core, as a cofactor. They are involved in electron transport chain and redox catalysis.
