What is a motif in a protein?

What is a motif in a protein?

Protein motifs are small regions of protein three-dimensional structure or amino acid sequence shared among different proteins. They are recognizable regions of protein structure that may (or may not) be defined by a unique chemical or biological function.

What is domain in gene?

(doh-MAYN) A specific physical region or amino acid sequence in a protein which is associated with a particular function or corresponding segment of DNA.

What is the difference between a protein domain and a protein subunit?

The key difference between protein subunit and domain is that a protein subunit is a separate polypeptide chain of a protein that assembles with other polypeptide chains to form a protein complex while, a protein domain is a contiguous region of the polypeptide chain of a protein that frequently folds independently …

What is the difference between a motif and a domain?

A motif is a short conserved sequence pattern associated with distinct functions of a protein or DNA. It is often associated with a distinct structural site performing a particular function. A domain is also a conserved sequence pattern, defined as an independent functional and structural unit.

What is the function of a motif?

A motif is a literary term that is an idea, object, or concept that repeats itself throughout a text. A motif gives clues to theme or reinforces ideas an author wants to emphasize. A motif generally reinforces the theme of the text.

What is the difference between domain and motif?

A motif is a short conserved sequence pattern associated with distinct functions of a protein or DNA. A domain is also a conserved sequence pattern, defined as an independent functional and structural unit. Domains are normally longer than motifs.

What is domain and motif?

How do you determine the domain of a protein?

One way to identify a domain is to find the part of a target protein that has sequence or structural similarities with a template through homology alignment. Another way is to predict the domain boundaries from a protein sequence.

What is a motif in biochemistry?

Biochemistry. Sequence motif, a sequence pattern of nucleotides in a DNA sequence or amino acids in a protein. Short linear motif, a stretch of protein sequence that mediates protein–protein interaction. Structural motif, a pattern in a protein structure formed by the spatial arrangement of amino acids.
