THE NUMBERING SCHEME FOR THE I-A(G7) RESIDUES IS AS REMARK 999 DESCRIBED IN "SEQUENCES OF PROTEINS OF IMMUNOLOGICAL REMARK 999 INTEREST" (1991), EDITED BY E.A. KABAT, T.T. WU, H.M. REMARK 999 PERRY, K.S. GOTTESMAN AND C. FOELLER. REMARK 999 DIMERIZATION OF THE I-A(G7) HETERODIMER WAS FACILITATED BY REMARK 999 ADDING A LEUCINE ZIPPER TAIL TO THE CARBOXY TERMINUS OF REMARK 999 EACH CHAIN. IN ADDITION, A HEXAHISTIDINE SEQUENCE WAS REMARK 999 ENGINEERED TO THE CARBOXY TERMINAL END OF THE LEUCINE REMARK 999 ZIPPER. THIS ALLOWED THE SECRETED PROTEIN TO BE PURIFIED REMARK 999 BY NI-NTA CHROMATOGRAPHY. A THROMBIN CUT SITE WAS REMARK 999 ENGINEERED IN A SPACER SEQUENCE BETWEEN THE CARBOXY REMARK 999 TERMINAL RESIDUE OF EACH CHAIN AND THE LEUCINE ZIPPER- REMARK 999 HEXAHISTIDINE SEQUENCE SO THAT MOST OF THE ENGINEERED REMARK 999 RESIDUES COULD BE REMOVED FOR CRYSTALLIZATION. AFTER REMARK 999 THROMBIN DIGESTION, EIGHT ENGINEERED RESIDUES (SSADLVPR) REMARK 999 REMAINED ATTACHED TO THE CARBOXY TERMINAL END OF EACH REMARK 999 I-A(G7) CHAIN. REMARK 999 NO ELECTRON DENSITY WAS VISIBLE FOR 1) THE FIRST 2 RESIDUES REMARK 999 OF THE ALPHA CHAIN 2) THE LAST 6 RESIDUES OF THE SPACER REMARK 999 SEQUENCE ATTACHED TO THE C-TERMINUS OF THE ALPHA CHAIN, REMARK 999 3) THE 6 RESIDUE (GSGSGS) LINKER BETWEEN GAD65 AND THE BETA REMARK 999 CHAIN, 4) THE FIRST 4 RESIDUES OF THE BETA CHAIN, AND 5) REMARK 999 THE LAST 7 RESIDUES OF THE SPACER SEQUENCE ATTACHED TO THE REMARK 999 C-TERMINUS OF THE BETA CHAIN. SIX ADDITIONAL RESIDUES REMARK 999 (GSHSRG) FROM THE SIGNAL SEQUENCE REMAIN CONNECTED TO THE REMARK 999 AMINO TERMINUS OF THE GAD65 PEPTIDE; NO DENSITY IS PRESENT REMARK 999 FOR THESE RESIDUES.
