It is associated with an electron-transport chain comprising b- and c-type cytochromes only, differing proportions of which are reduced by nicotinate and NADH. CO difference-spectra show two CO-binding pigments, cytochrome o (absorption maximum at 417nm) and another component absorbing maximally at 425nm. Cytochrome o is not reduced by NADH or by succinate but is by nicotinate, which can also reduce the \u2018425\u2019 CO-binding pigment. The effects of inhibitors of terminal oxidation support the idea of two terminal oxidases and a scheme involving the \u2018425\u2019 CO-binding pigment and the other components of the electron-transport chain is proposed.<\/jats:p>","DOI":"10.1042\/bj1290755","type":"journal-article","created":{"date-parts":[[2015,8,10]],"date-time":"2015-08-10T19:46:11Z","timestamp":1439235971000},"page":"755-761","update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["The oxidation of nicotinic acid by <i>Pseudomonas ovalis<\/i> Chester.
