PROMALS3D: a tool for multiple protein sequence and structure alignments.

@article{citeulike:2518424, abstract = {Although multiple sequence alignments (MSAs) are essential for a wide range of applications from structure modeling to prediction of functional sites, construction of accurate MSAs for distantly related proteins remains a largely unsolved problem.
