title: The functional localization of cytochromes b in the respiratory chain of anaerobically grown Proteus mirabilis.
abstract: The functional localization of the cytochromes b found in anaerobically grown Proteus mirabilis was investigated. From light absorption spectra, scanned during uninhibited and HQNO-inhibited electron transport to various electron acceptors, it was concluded that all cytochromes b function between two HQNO inhibition sites, or more probably in a Q- or b-cycle.
