Notes:
Two highly stable cysteine proteases, ervatamin B (ERV-B) and ervatamin C (ERV-C), purified from the latex of the medicinal plant E. coronaria have been crystallized at room temperature. Crystals of ERV-B and ERV-C diffract to 2.5 and 2.6 Å, respectively. The space group is P212121 for the crystals of both proteases with unit-cell parameters a = 47.5, b = 58.8 and c = 68.8 Å, and a = 43.8, b = 82.6 and c = 133.1 Å, respectively. A self-rotation function for ERV-C indicates a twofold non-crystallographic symmetry relating the two molecules in the asymmetric unit.
