| Short Name | Phytocyanin |
| description | Phytocyanins are blue copper proteins found in chloropasts of higher plants. They can be further subdivided into uclacyanins, stellacyanins, plantacyanins, and early nodulins. Stellacyanins have a blue copper coordinated by two His, one Cys and one Gln. In plantacyanins and uclacyanins, the ligands of the type-I Cu sites are two His, one Cys and one Met [, , , ]. Early nodulins lack amino acid residues that coordinate Cu, so they are believed to be involved in unknown processes without binding Cu []. |
