Purification and characterization of two membrane-bound c-type cytochromes from a facultative alkalophilic Bacillus.
The membrane fraction of the facultative alkalophilic bacterium, Bacillus YN-2000, was found to contain considerably larger amounts of two c-type cytochromes, cytochromes c-553 and c-552, when theExpand
