The cysteine-rich N-terminal domain of the micronemal adhesive protein MIC1 (MIC1-NT) from Toxoplasma gondii was cloned, expressed in Escherichia coli and purified. MIC1-NT is amenable to structural studies as shown by preliminary NMR and X-ray analysis. Positive results with two further micronemal proteins indicate that our strategy has wider application.
