The crystallization condition is consisting of PEG400, NaCl, MgCl2 and Sodium citrate. The protein was purified in HEPES buffer. I can see an unidentified electron density blob in coot and I am not able to figure out what it could be? I have attached the snapshot of that blob with this mail. I request everyone to please help me in identification of this blob. Thanking you in advance.
