C [auth M], D [auth W]	PF04234	CopC domain (CopC)	CopC domain	CopC is a bacterial blue copper protein that binds 1 atom of copper per protein molecule. Along with CopA, CopC mediates copper resistance by sequestration of copper in the periplasm [1].	Domain
B	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
A	PF07992	Pyridine nucleotide-disulphide oxidoreductase (Pyr_redox_2)	Pyridine nucleotide-disulphide oxidoreductase	This family includes both class I and class II oxidoreductases and also NADH oxidases and peroxidases. This domain is actually a small NADH binding domain within a larger FAD binding domain.	Domain

This domain is located centrally in Sulfide dehydrogenase [flavocytochrome c] flavoprotein chain from the proteobacteria Allochromatium vinosum, a component of the enzyme that catalyses the reversible conversion of sulphide to elemental sulfur in vitro. This domain is C-terminal to Pfam:PF07992 and N-terminal to Pfam:PF09242. This domain shows a five-stranded parallel beta-sheet flanked on one side by three alpha-helices and on the other side by a three-stranded anti parallel beta-sheet [1].	Domain
A	PF09242	Flavocytochrome c sulphide dehydrogenase, flavin-binding (FCSD-flav_bind)	Flavocytochrome c sulphide dehydrogenase, flavin-binding	Members of this family adopt a structure consisting of a beta(3,4)-alpha(3) core, and an alpha+beta sandwich. They are required for binding to flavin, and subsequent electron transfer [1].	Domain
