Primary structure similarity analysis of proteins sequences by a new graphical representation

Abstract: A new graphical description of the primary structure of protein sequences is introduced. First, a three-dimensional space discrete point set of a protein sequence is created based on the three main physicochemical properties of the amino acids. Secondly, a continuous cubic B-spline curve interpolating the amino acid points is constructed to represent the shape of the protein sequence. Then the geometric properties (curvature and torsion) of the continuous curve are extracted for the purpose of analyzing the si… Show more

“…Several computing methods measure the distance between multidimensional vectors, such as Hamming distance (HD), Euclidean distance, Elastic-matching distance, Jeffrey and Matusita distance, Manhattan distance, and Minkowski norm. Reportedly, these methods have little effect on the vector similarity [38]. The HD between two binary strings is defined by the number of bits in which they vary [39,40].…”

“…The protein shape analysis plays an important role in medical research, computer aided molecular design, protein structure retrieval and prediction, among others. However, the analysis is highly challenging due to the complexity of a protein’s three-dimensional surface shape, which can deform significantly enough to change the topological structure during molecular interactions [ 1 ].…”
