ALIGN: a program to superimpose protein coordinates, accounting for insertions and deletions

The alignment and superposition of protein structures are sometimes complicated by the presence of insertions or deletions in one structure or the other. The program ALIGN Satow, Cohen, Padlan & Davies (1986). J. Mol. Biol. 190, 593–604 was written to address this problem. The program provides information in its analysis of results to facilitate the understanding of transformations between structurally homologous subunits of protein structures.
