THE STRUCTURES WERE CALCULATED USING THE SIMULATED
ANNEALING PROTOCOL OF NILGES ET AL. (1988) FEBS LETT. 229,
129-136 USING THE PROGRAM CNS MODIFIED TO INCORPORATE
COUPLING CONSTANT RESTRAINTS (GARRETT ET AL. (1984) J. MAGN.
RESON. SERIES B 104, 99-103), CARBON CHEMICAL SHIFT
RESTRAINTS, (KUSZEWSKI ET AL. (1995) J. MAGN. RESON.
SERIES B 106, 92-96) RESTRAINTS, AND RESIDUAL DIPOLAR
COUPLING RESTRAINTS (CLORE ET AL. J. MAGN. RESON 131,
159-162 (1998); J. MAGN 133, 216-221(1998)).
IN THIS ENTRY THE LAST COLUMN REPRESENTS THE AVERAGE RMS
DIFFERENCE BETWEEN THE INDIVIDUAL SIMULATED ANNEALING
STRUCTURES AND THE MEAN COORDINATE POSITIONS. THE LAST
COLUMN IN THE INDIVIDUAL SA STRUCTURES HAS NO MEANING.
FITTING TO GENERATE THE AVERAGE STRUCTURE IS WITH RESPECT
BEST TO RESIDUES 1 - 250 (RESIDUES 251 - 249 ARE DISORDERED
IN SOLUTION) OF ENZYME I AND RESIDUES 1-85 OF HPR.
RESIDUES 251-249 ARE OMITTED FROM THE MEAN STRUCTURE.

THE 3D STRUCTURE OF THE EIN-HPR COMPLEX WAS SOLVED
BY MULTI-DIMENSIONAL HETERONUCLEAR NMR AND IS BASED
ON 5475 EXPERIMENTAL NMR RESTRAINTS:'
INTRAMOLECULAR EIN NOES: 746 SEQUENTIAL (|I-J|1), 517
MEDIUM RANGE (1 < |I-J <= 5), 436 LONG RANGE (|I-J|>5)
INTERRESIDUE NOES AND 486 INTRARESIDUE NOES.
INTRAMOLECULAR HPR NOES: 247 SEQUENTIAL (|I-J|1), 167
MEDIUM RANGE (1 < |I-J <= 5), 246 LONG RANGE (|I-J|>5)
INTERRESIDUE NOES AND 202 INTRARESIDUE NOES.
