REMARK   2
REMARK   2 From 2D NOE measurements of the complex in
REMARK   2 aqueous solution a total of 508 distances was derived,
REMARK   2 of which 260 are within the headpiece, 212 within the
REMARK   2 operator and 36 between headpiece and the operator.
REMARK   2 Most of these distances were measured by analysing the
REMARK   2 initial rate of the NOE buildup as a function of the mixing
REMARK   2 time. A number of known and fixed distances were used to
REMARK   2 define a calibration scale. Computed interproton distances
REMARK   2 were converted to upper and lower distance bounds by adding
REMARK   2 or subtracting 10 percent of the distances. Pseudo-atom
REMARK   2 corrections, if needed, were applied afterwards. For most
REMARK   2 protein-DNA contacts the buildup rates were considered to 
REMARK   2 be less reliable, and upper bound estimates of 4 or 6 
REMARK   2 Angstrom were used.
REMARK   2 In total 508 upper bound and 472 lower bound constraints
REMARK   2 were obtained.
