Crystallization and preliminary X-ray crystallographic analysis of human peptidylarginine deiminase type III

Human peptidylarginine deiminase type III was crystallized using polyethylene glycol monomethylether or polyethylene glycol as a precipitant. The crystals belonged to space group R3, with unit-cell parameters a = b = 114.97, c = 332.49 Å (hexagonal axes), and contained two molecules in an asymmetric unit.
