  • Prediction of unknown biological function of the active site in proteins or/and polynucleotides, and its utilization
    Publication number: 20040049350
    Abstract: Biological•functional activity or binding partner of an arbitrary amino acid sequence (or nucleotide sequence) is efficiently predicted by giving EIIP index values to the total amino acid sequence or nucleotide sequence of a natural-type or non-natural-type arbitrary protein, and comparing the frequency spectra obtained by subjecting the resulting EIIP sequences to DFT.
