Welcome to Phytocyanins !

Blue copper proteins containing a single type I mononuclear copper site are known as phytocyanins (PCs) in plants which they are associated with electron carrier activity. The phytocyanin domain has a core β-sandwich comprising seven β-strands, and a disulfide bridge closing the metal centre is a characteristic feature. Based on the ligand composition of the copper-binding site, the glycosylation state, the domain structure, and the spectral characteristics, PCs can be grouped into four subfamilies: uclacyanins (UCs), plantacyanins (PLCs), stellacyanins (SCs) and early nodulin-like proteins (ENODLs). PCs exert an important part in growth and development of plants, in addition to the influence of their spectroscopic and redox properties.
