| Short Name | Halocyanin |
| description | Halocyanins are blue (type I) copper redox proteins found in halophilic archaea such as Natronomonas pharaonis (Natronobacterium pharaonis). Halocyanin from from N. pharaonis has been characterised and shown to be a small blue copper protein with a molecular mass of about 15.5kDa [, ]. This protein, which was named halocyanin, contains one Cu2+, with a copper-binding site containing two His, one Met, and one Cys as probable ligands. It is probable that halocyanin is a peripheral membrane protein, which serves as a mobile electron carrier.This entry represents the copper-binding domain of halocyanins. This domain is present only once in some halocyanins and is duplicated in others. It is not found in plastocyanins or certain divergent paralogs of halocyanin. |
