Abstract:SynopsisThe crystal structure of the c-type cytochrome NirC from Pseudomonas aeruginosa has been determined and reveals the simultaneous presence of monomers and 3D-domain-swapped dimers in the same asymmetric unit.Abstract Monoheme c-type cytochromes are important electron transporters in all domains of life.They possess a common fold hallmarked by three α-helices that surround a covalently attached heme.An intriguing feature of many monoheme c-type cytochromes is their capacity to form oligomers by exchangin… Show more
