Plastocyanin is a copper-containing protein that mediates electron-transfer. It is found in a variety of plants, where it participates in photosynthesis . The protein is a prototype of the blue copper proteins , a family of intensely blue-colored metalloproteins .

Plastocyanin is a 10 kD blue copper protein which is located in the lumen of the thylakoid where it functions as a mobileelectron carrier shuttling electrons from cytochromef to P700 in Photosystem I. PC is a typical β-barrel protein containing a single copper center which is ligated to two histidines, a methionine and a cysteine in a ...

Plastocyanin is a small, acidic, blue copper protein found in most oxygenic phototrophs. The structure of Chlamydomonas plastocyanin has been determined by X-ray crystallography to a resolution of 1.5 Å (Redinbo et al., 1993). Like plastocyanin from other species, it is an antiparallel β-barrel possessing a single copper atom that is ...

Plastocyanin is one of the best characterized of the photosynthetic electron transfer proteins. Since the determination of the structure of poplar plastocyanin in 1978, the structure of algal (Scenedesmus, Enteromorpha, Chlamydomonas) and plant (French bean) plastocyanins has been determined either …

Plastocyanin (PC) is the small soluble Cu protein in the thylakoid lumen, mediating the electron transfer from Cyt b 6 /f to PSI (Table 1 and Figure 1). In arabidopsis, two PC isoforms are encoded that have an equivalent essential function in electron transport activity.

The name plastocyanin was introduced by Katoh and Takamiya in the early 1960s when isolating this protein from spinach chloroplasts (Katoh 2003). Plastocyanin from poplar was the first blue copper protein to be structurally characterized, and its structure was determined by the Freeman group in 1978 (Colman et al. 1978 ).

Plastocyanin (Pc) is a copper (Cu)-containing blue protein, that functions as a mobile electron carrier between cytochrome (cyt) f and Photosystem 1 (PS1) in oxygenic organisms. The atomic structure is known and can be described as a β-barrel with hydrophobic residues in …

1993年5月6日 · Plastocyanin is a small (98 amino acids), blue copper-binding protein that catalyzes the transfer of electrons in oxygenic photosynthesis from cytochrome f in the quinol oxidase complex to P700+ in photosystem I. Chlamydomonas reinhardtii plastocyanin is an eight-stranded, antiparallel beta-barrel with a single copper atom coordinated in ...

2020年10月2日 · Plastocyanin is a small copper-containing protein found in cyanobacteria, higher plants, and some algae, where it plays a role in photosynthesis. The two photosystems that are primarily responsible for photosynthesis are photosystem I (PSI) and photosystem II (PSII).
