    Notes: A large distance between the reactor core and the monochromator together with a take-offangle of 90° leads to low flux but high angular resolution of the diffractometer around 90° scatteringangle. The sample-table consists of two goniometers for heavy loads. An x-y-z table for heavy loadscan be mounted, as well as different eulerian cradles, a mirror furnace or a tensile rig. The detectoris a 20x20cm2 position sensitive delay-line detector made by EMBL. A sophisticated primary andsecondary slit system together with the recently installed high-resolution camera system allows theapplication of the high precision instrument alignment and calibration system recently developed atHMI. Here some special features of the instrument are presented and the consequences are outlined

    Notes: The maintenance of protein function and structure constrains the evolution of amino acid sequences. This fact can be exploited to interpret correlated mutations observed in a sequence family as an indication of probable physical contact in three dimensions. Here we present a simple and general method to analyze correlations in mutational behavior between different positions in a multiple sequence alignment. We then use these correlations to predict contact maps for each of 11 protein families and compare the result with the contacts determined by crystallography. For the most strongly correlated residue pairs predicted to be in contact, the prediction accuracy ranges from 37 to 68% and the improvement ratio relative to a random prediction from 1.4 to 5.1. Predicted contact maps can be used as input for the calculation of protein tertiary structure, either from sequence information alone or in combination with experimental information. © 1994 John Wiley & Sons, Inc.
