Searching results of the ultrabithorax homeodomain protein. Searching results using the homeotic Ubx/Exd/DNA ternary complex (PDB entry 1B8I-A) from Drosophila melanogaster as the query. (A) The contact residues of 1B8I-A complex are presented as stick (yellow). The sequence of 1B8I-A is shown and contact residues are marked with asterisks. (B) Structure alignment of 1B8I-A (blue) and 1PUF-A (green). The score is 4.78 and Z-score is 11.92 by our scoring method. (C) Structure alignment of 1B8I-A (blue) and non-DNA-binding protein 1BOB (green). Only the aligned structure/sequence of 1B8I-A and 1BOB are shown. We obtained score = -0.72 and Z-score = 0.58.
