3.D.4.8.1
Cytochrome oxidase (Cox).  The factors limiting the allotopic production of the Cox2 subunit of yeast cytochrome c oxidase have been discovered (Nieto-Panqueva et al. 2024). The biogenesis pathway followed by the allotopically produced Cox2 subunit based on the participation of the 2 different structural/functional forms of the TIM23 translocon, TIM23MOTOR and TIM23SORT must follow a concerted and sequential mode of action to insert Cox2W56R into the inner mitochondrial membrane in the correct Nout-Cout topology (Nieto-Panqueva et al. 2024). The Plasmodium falciparum putative SURF1 protein can functionally replace SHY1, a COX assembly factor of complex IV of the mitochondrial electron transfer complex of Saccharomyces cerevisiae (Chellappan et al. 2021).
