LALNVIEW - A GRAPHICAL VIEWER FOR PAIRWISE SEQUENCE ALIGNMENTS

LALNVIEW is a graphical program for visualising local alignments betwe en two sequences (protein or nucleic acids). Sequences are represented by coloured rectangles to give an overall picture of their similariti es. LALNVIEW can display sequence features (exon, intron, active site, domain, propeptide, etc.) along with the alignment. When using LALNVI EW through our Web servers, sequence features are automatically extrac ted from database annotations (SWISS-PROT, GenBank, EMBL or HOVERGEN) and displayed with the alignment. LALNVIEW is a useful tool for analys ing pairwise sequence alignments and for making the link between seque nce homology and what is known about the structure or function of sequ ences. LALNVIEW executables for UNIX, Macintosh and PC computers are f reely available from our server (http://expasy.hcuge.ch/sprot/lalnview .html).
