Crystallization and subunit structure of canine myeloperoxidase

Three crystal forms of canine myeloperoxidase are described. An orthorhombic form in space group P212121 has unit cell dimensions: a = 108.3 Å (1 Å = 0.1 nm) b = 205.9 Å and c = 139.9 Å. A trigonal form in space group P3121 or P3221 has unit cell dimensions: a = b = 138.9 Å and c = 145.2 Å. A monoclinic form in space group C2 has unit cell dimensions: a = 117.2 Å, b = 96.9 Å, c = 131.4 Å and β = 116.3 °. Unusual features in the...
