Methods for predicting protein activity based on identification of multidimensional signatures
The present invention provides a method for predicting antimicrobial activity of a candidate protein by determining the correlation between a multidimensional antimicrobial signature and a multidimensional antimicrobial signature model. The invention also is directed to a method for identifying a protein having antimicrobial activity by screening a library of candidate proteins to identify a multidimensional antimicrobial signature. Also provided by the invention is a method for improving the antimicrobial activity of a protein by altering the multidimensional antimicrobial signature of the protein to increase the similarity to a multidimensional antimicrobial signature model.
1 . A method for predicting antimicrobial activity of a candidate protein comprising determining the the presence a multidimensional antimicrobial signature in a candidate protein, and comparing said multidimensional antimicrobial signature to a multidimensional antimicrobial signature model, whereby the degree of similarity between the multidimensional antimicrobial signature to the multidimensional antimicrobial signature model is predictive of antimicrobial activity.
2 . A method for identifying a protein having antimicrobial activity comprising screening a library of candidate proteins to identify a multidimensional antimicrobial signature in a candidate protein, and comparing said multidimensional antimicrobial signature to a multidimensional antimicrobial signature model, whereby the degree of similarity between the multidimensional antimicrobial signature to the multidimensional antimicrobial signature model is predictive of antimicrobial activity.
3 . A method for improving the antimicrobial activity of a protein comprising altering the multidimensional antimicrobial signature of the protein to increase the degree of similarity between said multidimensional antimicrobial signature and a multidimensional antimicrobial signature model, thereby improving the antimicrobial activity of the protein.
4 . A method for designing a protein having antimicrobial activity comprising incorporation of configurations comprising iterations of a γ-core signature in a peptide structure.
