POLINA: detection and evaluation of single amino acid substitutions in protein superfamilies
1Department of Anatomy and Structural Biology, Albert Einstein College of Medicine, Bronx, NY 10461, USA. slevin@aecom.yu.edu
Motivation And Results:
An algorithm is described for the quick identification and evaluation of amino acid substitutions in multiple protein sequence alignment. The strategy is based on the calculation of a relative conservation index for an amino acid at each position of the alignment. The algorithm is implemented in the computer program POLINA (Protein Oriented LINear Analysis) which provides a summary of analysis in a format suitable for import into a graphing program.
