UbiB proteins mediate an ATP-dependent decarboxylation step in bacterial ubiquinone biosynthesis.
Polyisoprenoid quinones such as ubiquinone (UQ) play an essential role in cellular physiology, acting as membrane-bound electron and proton carriers in respiratory chains and other biological processes across all domains of life. In Escherichia coli, the canonical UQ biosynthesis pathway is well characterized. It invol...
