The database of Phylogeny and ALIgnment of homologous protein structures (PALI) contains structure-based sequence alignments and dendrograms based on information primarily derived from the structural alignments at domain level [1,2]. Protein domain decomposition as proposed by SCOP (Version 1.75C) is used in the PALI database (version 2.8c) [3]. Non-redundant entries with best resolution corresponding to each SCOP domain family are used for the structural alignments.
