Plastocyanin Cu(II) form.

thingiverse

Human: Plastocyanin is also known as blue copper protein and plays a key role in electron-transfer processes: http://en.wikipedia.org/wiki/Plastocyanin The model shows the Cu II form of plastocyanin with four ligands attached to the copper (II) ion. These are nitrogen from His37, sulfur from Cys84, nitrogen from His87, and sulfur from Met92. This protein model is based on the structure identified by the Protein Data Bank entry 1PLC: http://www.rcsb.org/pdb/explore/explore.do?structureId=1plc An STL file for plastocyanin was created using VMD: http://www.ks.uiuc.edu/Research/vmd/ In this model, the protein backbone is represented as a "cartoon". The histidines, cysteine and methionine that bind to copper are clearly shown, along with the copper ion itself. Plastocyanin Model for Coloring by Hand Plastocyanin was successfully printed using a Replicator 2 in PLA with MakerWare(TM) 2.4.1.24 software. The print settings used standard resolution with three shells and 25% infill, along with a raft and supports. Different views of the model are provided to help users color it by hand.
