The 2,2,6,6-tetramethylpiperidine-1-oxyl-4-amino-4-carboxylic acid is a nitroxide spin-labeled, achiral C a -tetrasubstituted a-amino acid that has recently been shown to be an effective b-turn and 3 10 /a-helix inducer in peptides and an excellent and relatively rigid electron spin resonance probe
## Abstract Local determinants of 3~10~‐helix stabilization have been ascertained from the analysis of the crystal structure data base. We have clustered all 5‐length substructures from 51 nonhomologous proteins into classes based on the conformational similarity of their backbone dihedral angles.
