Complex I is the largest protein complex of the oxidative phosphorylation system in mitochondrial and it catalyzes NADH-quinone oxidoreduction. Complex I represents the main entrance site for electrons into the respiratory electron transfer chain. In Arabidopsis, Complex I have at least 49 subunits and AT4G16450 is one of the subunit.

Complex I represents the main entrance site for electrons into the respiratory electron transfer chain. In Arabidopsis, Complex I have at least 49 subunits and PSST (AT5G11770) is one of the subunit, which is also designated 20 kDa subunit.
FTSH4 is an FtsH protease that is localized to the mitochondrion. Loss of function results in increased determinacy of the meristem that is exacerbated when plants are grown at higher temperatures.
FTSH10 is localized to the mitochondrion, it is involved in the assembly and/or stability of the complexes I and V of the mitochondrial oxidative phosphorylation system.
