Abstract
The gene coding for agglutinin from Galanthus nivalis (GNA) was expressed in, and secreted by, the methylotrophic yeast, Pichia pastoris. Transformants of P. pastoris were selected and a process to produce and purify gram quantities of recombinant GNA was developed. GNA was secreted at approximately 80 mg l−1 at the 200 l scale and was purified to 95% homogeneity using hydrophobic interaction chromatography. The recombinant protein was similar to the protein synthesised in plant with respect to structure and biological activity.
