A, C, E	PF21342	SoxA/TsdA, cytochrome c domain (SoxA-TsdA_cyt-c)	SoxA/TsdA, cytochrome c domain	This entry represents the first cytochrome c domain of SoxA and TsdA proteins, heme proteins involved in sulfur oxidation [1-5].	Domain
B, D, F	PF00034	Cytochrome c (Cytochrom_C)	Cytochrome c	The Pfam entry does not include all Prosite members. The cytochrome 556 and cytochrome c' families are not included. All these are now in a new clan together. The C-terminus of DUF989, Pfam:PF06181, has now been merged into this family.	Domain
