| Abstract: | Identification of conservative and variable regions of an amino acid sequence of a protein is important for predicting its structure and functions. Based on the purposes, an entropy computation software named Entropy, with functions of frequencies calculation of single amino acid residue and generation of conservative sequence, was designed and realized, and which was applied to analyze the features of amino acid sequence of hemagglutininprotein of influenza A virus. The software described in this study provides a useful tool for amino acid sequence analysis. |
