Purified native plastocyanin from Spinacia oleracea UniProt: P00289
Plastocyanin (PC) is a small Cu protein and a mobile electron carrier in the lumen of the thylkoids. PC interacts with the B/F complex and Photosystem I. Alternative name: DNA-damage-repair/toleration protein DRT112.
Plastocyanin runs abberant due to negative charge at 12-19 kDa on SDS-PAGE depending upon the system used. in 15% gel the protein will run closer to its true MW than in 12% gel. In some cases PC can be very acidic and run at twice of its MW.PC1 runs closer to 14 kDa while PC2 runs closer to 19 kDa. For good resolution adding fresh DTT to the sample buffer is recommended. PC2 is generally more abundant and it increases with Cu feeding. PC1 is expressed first after etiolated seedlings are placed in the light.
