The construct has tags (flag and his) and protease cleavage site at its N-term (DYKDDDDKHHHHHHHHHHLEVLFQGP) and when compared to uniprot it starts at 21 and ends at 856. For CryoEM, the tag is cleaved and the protein used for experiment starts at QSSE but residues starting from RR have been modeled. There are 5 thermostabilising mutations (T742A, S753A, T777A, I799A, A813L). Residue N445 is mutated to remove glycosylation. An additional mutation H350L is engineered for a nanobody to bind. Each monomer has one sugar modelled and 10 disulfide bonds.
