Crystallization and preliminary X-ray studies on the mannose-specific lectin from Amaryllis bulbs

Affinity-purified amaryllis lectin was used to grow single crystals using the hanging-drop method. The space group was found to be C2 with unit-cell dimensions a = 73.4 (1), b = 100.3 (1), c = 62.2 (1) A and beta = 137.3 (2) degrees. Data to 2.25 A resolution have been recorded and solution of the structure is currently underway by means of molecular-replacement techniques.
