Backbone Dihedral Angles of Triose Phosphate Isomerase (8TIM)

Description

A dataset consisting of 490 pairs of backbone dihedral angles (in radian scale [0, 2\pi) ) (\phi, \psi) for the protein Triose Phosphate Isomerase (8TIM). The angles were obtained first by using the DSSP software on the PDB file for 8TIM to get the backbone angles (in degrees), and then by converting all angles into radians. Due to the presence of different secondary structures (helices, sheets and loops) in the protein, the angular data show considerable variability, and is multimodal with noticeably distinct clusters.

Usage

data(tim8)

Format

A data frame with 490 rows and 2 variables (backbone dihedral angles) phi and psi.
