COHEN ET AL. (PDB ENTRY 2GCH). SECONDARY STRUCTURE ELEMENTS AND REMARK 3 SEQUENCE DATA ARE IDENTICAL TO THOSE OF ENTRY 2GCH EXCEPT THAT THE REMARK 3 USE OF CRYOCRYSTALLOGRAPHY TECHNIQUES AND THE EXTENDED RESOLUTION REMARK 3 OF THE CURRENT STUDY PERMITTED ASSIGNMENT OF COORDINATES TO REMARK 3 RESIDUES 149 AND 150, REMARK 3 WHICH ARE ADJACENT TO A NATURAL EXCISSION SITE. INITIAL PHASES REMARK 3 WERE DERIVED FROM THE 2GCH MODEL. A PREVIOUS ENTRY BY BRADY ET AL. REMARK 3 (PDB ENTRY 6GCH) DESCRIBES AN IDENTICAL COMPLEX DETERMINED BY REMARK 3 CRYSTAL STRUCTURE ANALYSIS AT LOWER RESOLUTION (2.1 ANGSTROM). REMARK 3 MORE ACCURATE DETERMINATION OF HYDROGEN BONDING DISTANCES WITHIN REMARK 3 THE CATALYTIC TRIAD MOTIVATED THE CURRENT STUDY.
