The N-terminal sequence (DYKDDDDKHHHHHHHHHHLEVLFQGP) is the tag and linker), which has been cleaved by protease before structural experiment. Here, it is included for completion. The sequence when compared to uniprot starts at 21 and ends at 856 (construct used for expression). The construct has the following mutations (with reference to Uniprot ID P41594) H350L - mutation for nanobody binding T742A, S753A, T777A, I799A, A813L (thermostabilising mutant) W785A - introduced mutant to test for PAM binding. There are 10 disulfide bonds per chain and 2 NAG molecules.
