A	PF07732	Multicopper oxidase (Cu-oxidase_3)	Multicopper oxidase	This entry contains many divergent copper oxidase-like domains that are not recognised by the Pfam:PF00394 model.	Domain
A	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
