Characterization of Cytochrome Mutants in Outer and Periplasmic Membranes
This study investigates various putative outer-membrane and periplasmic cytochrome mutants, including knocked-out variants such as ΔomcC, ΔomcB, and others. We analyze their effects on U(IV) uptake in wild-type strains and mutant strains, providing insights into the roles of specific cytochromes (e.g., ΔppcA, ΔmacA) in metal ion transport and cellular metabolism. The findings contribute to a better understanding of electron transport mechanisms in bacteria and their implications for bioremediation processes.
