Purification and characterisation of cytochrome c’ from Neisseria meningitidis
Huston, Wilhelmina M., Lowe, Elisabeth C., Butler, Clive S., & Moir, James W. B. (2005) Purification and characterisation of cytochrome c’ from Neisseria meningitidis. Biochemical Society Transactions, 33(5), pp. 187-191.
Cytochrome c', a c-type cytochrome with unique spectroscopic and magnetic properties, has been characterized in a variety of denitrifying and photosynthetic bacteria. Cytochrome c' has a role in defence and/or removal of NO but the mechanism of action is not clear. To examine the function of cytochrome c' from Neisseria meningitidis, the protein was purified after heterologous overexpression in Escherichia coli. The electronic spectra of the oxidized c' demonstrated a pH-dependent transition (over the pH range of 6-10) typical of known c'-type cytochromes. Interestingly, the form in which NO is supplied determines the redox state of the resultant haem-nitrosyl complex. Fe(III)-NO complexes were formed when Fe(II) or Fe(III) cytochrome c' was sparged with NO gas, whereas an Fe(II)-NO complex was generated when NO was supplied using DEA NONOate (diazeniumdiolate).
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
