A summary of the localization and kinetics of key processes involved in arsenate respiration in Gram-negative bacteria. Arsenate is illustrated as H2AsO4, which is in equilibrium with HAsO42− with a pKa of 6.94. References for literature values are provided in the main text. IM, inner membrane; OM, outer membrane.
