Tree Number(s): G02.111.570.820.709.600.020
Unique ID: D000072756
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D000072756
Annotation: IM general only; coordinate NIM with specific protein
Scope Note: A secondary structure of proteins that is a right-handed helix or coil, where each amino (N-H) group of the peptide backbone contributes a hydrogen bond to the carbonyl(C=O) group of the amino acid four residues N-terminal to it (n-4). It is the most common type of secondary structure.
