HOWEVER, UPON SOLVING THE STRUCTURE IT BECAME CLEAR THAT THE C-TERMINAL DOMAIN HAD BEEN CLEAVED OFF IN THE DROP, LEAVING ONLY THE ASPARAGINASE CATALYTIC DOMAIN. SINCE THE EXACT LOCATION OF THE CLEAVAGE SITE IS UNKNOWN, THE SEQRES RECORDS IN THE PDB FILE ONLY INCLUDE THE 23-RESIDUE HIS TAG AND UNIPROT SEQUENCE DATABASE RESIDUES 1 THROUGH 362.
