Abstract
Aims: Based on protein sequence information, a simple and effective method was used to analyze protein sequence similarity and predict DNA-binding protein.
Background: It is absolutely necessary that we generate computational methods of low complexity to accurate infer protein structure, function, and evolution in the rapidly growing number of molecular biology data available.
Objective: It is important to generate novel computational algorithms for analyzing and comparing protein sequences with the rapidly growing number of molecular biology data available.
Methods: Based on global and local position representation with the curves of Fermat spiral and normalized moments of inertia of the curve of Fermat spiral, respectively, moreover, composition of 20 amino acids to get the numerical characteristics of protein sequences.
Results: It has been applied to analyze the similarity/dissimilarity of nine ND5 proteins, the analysis results are consistent with the biological evolution theory. Furthermore, we employ the Logistic regression with 5-fold cross-validation to establish the prediction of DNA-binding proteins model, which outperformed the DNAbinder, iDNA-prot, DNA-prot and gDNA-prot by 0.0069-0.609 in terms of F-measure, 0.293-0.898 in terms of MCC in unbalanced dataset.
Conclusion: These results show that our method, namely FermatS, is effective to compare, recognition and prediction the protein sequences.
Keywords: Fermat spiral, mass, moment of inertia, similarity/dissimilarity of species, identification of DNA-binding proteins, logistic regression.
