A program, BIOSITE, providing for the interactive visual comparison of aligned homologous amino-acid sequences is presented, including an example of its application. The program allows for two types of comparison sequence to be generated: an identity sequence and a difference sequence. These may be used on subsets of sequences and in further comparisons to identify candidate sites involved in a distinct functional property. The program should prove a useful tool for biologists engaged in understanding sequencefunction relationships.
