NMR実験の詳細
Text: 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. ...Text: 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.
