Inhibitors

Inhibitors	Comment	Organism	Structure
additional information	inhibition in the absence of Ca2+ is noted at potentials where heme 4 and/or 5 is reduced, this may implicate Ca2+ association with the propionate of heme 4 as being essential for maintaining steady-state activity from the fully reduced enzyme-substrate complex	Escherichia coli
