Modularly-assembled protein structure model

Abstract

The invention discloses a modularly-assembled protein structure model which is formed by repeatedly connecting common modules (peptide planar modules) and amino acid feature modules ([alpha] carbon atoms and side chain modules) in sequence, and connecting an amino module and a carboxyl module at two ends, namely, the amino module-an amino acid feature module 1-a common module 1-an amino acid feature module 2-a common module 2...an amino acid feature module n-the carboxyl module. According to the modularly-assembled protein structure model provided by the invention, peptide planes and [alpha] carbon atoms are taken as basic structure modules; a module which can accurately display spatial configuration of a primary structure, a secondary structure, a tertiary structure, a quaternary structure and the like of protein is established; and standard production and manufacturing of the model, understanding of students, and application to scientific research are facilitated.

Description

technical field [0001] The invention belongs to the technical field of teaching and scientific research appliances, and in particular relates to a protein structure model for modular assembly. Background technique [0002] Protein is a biomacromolecule with three-dimensional structure, which plays very important functions in life activities. The structure of protein has multiple levels such as primary structure, secondary structure, tertiary structure and quaternary structure. The understanding and research of protein spatial structure is an important part of studying the relationship between biomolecules and using biomacromolecules for production practice. ring. The conventional ball and stick model can well illustrate the structure of small chemical molecules. However, proteins have large molecular weights, many types and numbers of atoms, and complex spatial structure changes. Relying on balls and sticks to splice one by one, only some amino acids or simple polypeptide m...

Problems solved by technology

This method cannot accurately display the formation of peptide bonds and peptide planes, and it is also difficult to display dihedral angles. The spatial structure formed by paper clip hooks is inaccurate, arbitrary and misleading, and it is difficult to be applied in the field of scientific research.

[0004] In the existing teaching and research process of protein structure and function, there is no model that can simply and intuitively show the protein from the primary structure to the three-dimensional structure, causing some confusion to practitioners and students
