Entity 1, BRCT 116 residues - Formula weight is not available

Residues 1-16 i.e., first sixteen residues are from cloning vector; D17 to T103 in provided sequence is BRCT domain corresponding to native sequence for BRCT domain of M.tb LigA that starts from ASP 605 and runs uptil THR 691. Residues K104 to H116 are again from cloning vector containing 6X-HIS tag.
