The work is devoted to the consideration of regularities of spatial structure formation in proteins and their application in nanobioengineering. Methods for estimating the chirality of regular and irregular protein structure, as well as helical nanotubes based on phenylalanine are presented. The magnitude and the chirality sign of α-, 310-, and π-helices, β- and α-turns, Ω-loops, and right-handed and left-handed phenylalanine nanotubes have been calculated. The obtained results can be used to control the assembly of natural and artificial proteins.
