As others suggested, I would check the globularity of the fusion protein with biophysical technique such as SAXS, if possible.

If you decide to try this option of crystallizing a fusion protein of your target, I would consider using N-terminal but also C-terminal fusions. We have had success using MBP in N-ter and the superfolder GFP in C-terminal for a few 'vexing' proteins from Plasmodium falciparum. It helped us either to obtain crystals/structures (as you seek) but also provided a way to circumvent a tendency for twinning from our target in some specific cases. GFP has the added benefit that your fusion crystals should be bright yellow so that speeds up the screening process a bit. I hope this helps. Good luck Best regards, Pascal Egea, PhD UCLA School of Medicine ________________________________ To unsubscribe from the CCP4BB list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/WA-JISC.exe?SUBED1=CCP4BB&A=1<https://urldefense.com/v3/__https://www.jiscmail.ac.uk/cgi-bin/WA-JISC.exe?SUBED1=CCP4BB&A=1__;!!PfbeBCCAmug!zZxYLQsNYEE7cGG5xqck4mGlLhxy_RFp_9C-98qrEOdMHkcrQeVJ0b4Mrb0GrUXvIw$> <https://urldefense.com/v3/__http://mednet.ucla.edu__;!!PfbeBCCAmug!zZxYLQsNYEE7cGG5xqck4mGlLhxy_RFp_9C-98qrEOdMHkcrQeVJ0b4Mrb00MzwdbQ$> ________________________________ To unsubscribe from the CCP4BB list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/WA-JISC.exe?SUBED1=CCP4BB&A=1<https://urldefense.com/v3/__https://www.jiscmail.ac.uk/cgi-bin/WA-JISC.exe?SUBED1=CCP4BB&A=1__;!!PfbeBCCAmug!zZxYLQsNYEE7cGG5xqck4mGlLhxy_RFp_9C-98qrEOdMHkcrQeVJ0b4Mrb0GrUXvIw$> The information contained in this e-mail message may be privileged, confidential, and/or protected from disclosure.
