Additional NMR Experimental Information
Details	The author states that NMR was carried out on a single fragment (363-451) containing both fingers F1 and F2 of APLF, but the structure calculations were carried out separately for each finger. This co-ordinate file includes residues 405-451 and contains F2 as well as the unstructured regions on either side.
