Question

He terms motif (fold) and domain describe levels of protein organization more complicated than primary or secondary structure. differentiate between motifs and domains by moving each phrase to the appropriate bin. note: if you answer any part of this question incorrectly, a single red x will appear indicating that one or more of the phrases are sorted incorrectly.

Answer 1

The motif is the repetitive supersecondary structures, an example of a motif is a beta-alpha-beta unit. The motifs are formed of the clusters of secondary structure.  

On the other hand, the domains are globular and stable functional units in a protein. It may retain a three-dimensional configuration when distinguished from the rest of the protein.  

Both the motifs and domains are stabilized by the hydrophobic interactions, they both are a unit of tertiary structure, and are dependent on primary composition.  

Answer 2

A protein motif is a short evolutionary conserved region in the protein which may play important functions. Moreover, a protein domain is a longer conserved protein region that also may have important functions.

• The characteristics of the protein motifs include:

1. repetitive super-secondary structure. Supersecondary structures are protein regions composed of 10 to 40 amino acids observed in different proteins.
2. clusters of secondary structure. Clusters of secondary structure are regular short arrangements of adjacent amino acids in the polypeptide chain.
3. ßaß unit. The α helix and β sheet are the most common classes of protein secondary structures

• The characteristics of the protein domains include:

1. stable, globular units. The tertiary structure is the tridimensional structure of globular proteins
2. may retain a three-dimensional structure when separated from the rest of the protein. Protein domains are stable enough to conserve their 3D shape in absence of the protein.
3. may be distinct functional units in a protein. A protein may have different domains

• The characteristics of both protein motifs and protein domains include:

1. unit of tertiary structure. Protein domains and protein motifs are units of tertiary structure because they are composed of both alpha helices and beta sheets (i.e., units of secondary structure)
2. depends on the primary structure. Both protein domains and protein motifs depend on the arrangement of amino acids (i.e., the primary structure) in the polypeptide chain
3. stabilized by hydrophobic interactions

In conclusion, a protein motif is a short evolutionary conserved region in the protein which may play important functions. Moreover, a protein domain is a longer conserved protein region that also may have important functions.
