Abstract

The embodiment of the invention discloses a protein function prediction method and a protein function prediction device. The method comprises the following steps of obtaining amino acid sequence characteristics of a target protein and amino acid sequence characteristics of a reference protein; based on the amino acid sequence characteristics of the target protein and the amino acid sequence characteristics of the reference protein, judging whether the functions of the target protein and the reference protein meet a similarity judgment rule or not; and if yes, determining the function of the target protein according to the function of the reference protein. The similarity between the function of the target protein and the function of the reference protein is judged from the deep feature level of the amino acid sequence related to the function, so that the influence of the ambiguity of the surface feature of the amino acid sequence on the function similarity judgment can be avoided. Thecoverage rate of protein function prediction is improved.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a protein function prediction method and device. Background technique [0002] Proteins are composed of 20 natural amino acids through linear combinations. These linear sequences contain a large amount of characteristic information of living organisms, and are generally considered to be able to explain and express all life activities in the body. The function of a protein is determined by its amino acid sequence, and proteins with similar functions usually have similar sequence fragments [0003] Based on the assumption that proteins with similar sequences will have similar structures and functions, in order to realize the function prediction of the target protein, amino acid multiple sequence alignment technology (such as Basic Local Alignment Search Tool, BLAST) is usually used to search and identify the target protein. Known functional proteins with similar ...
