Motif definition and specification. A) Structural motif involving residues His57, Asp102 and Ser195 of 1a0j, and interactively measured distances, as rendered by Swiss-PdbViewer (with legibility enhancements). B) Textual representation of the motif specification corresponding to the image in Figure 1 (the secondary structure constraints have subsequently been set to “*” using a text editor).
