MeSH Heading: Amino Acid Motifs
Tree Number(s): G02.111.570.820.709.275.500; G02.111.570.820.709.600.500
Unique ID: D020816
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D020816
Annotation: IM general only; coordinate NIM with specific protein
Scope Note: Three-dimensional protein structural elements that are composed of a combination of secondary structures. They include HELIX-LOOP-HELIX MOTIFS and ZINC FINGERS. Motifs are typically the most conserved regions of PROTEIN DOMAINS and are critical for domain function. However, the same motif may occur in proteins or enzymes with different functions.
