What is a superfamily in biology?

Definition of superfamily

1 : a category of biological classification ranking below an order and above a family. 2 : a large group of closely related molecules or chemical compounds usually possessing a similar function.

What is superfamily in bioinformatics?

SUPERFAMILY is a database and search platform of structural and functional annotation for all proteins and genomes. It classifies amino acid sequences into known structural domains, especially into SCOP superfamilies. Domains are functional, structural, and evolutionary units that form proteins.

How many protein superfamilies are there?

Therefore, whilst studies have suggested that there may be approximately 100 thousand protein families [16, 19] many proteins can be decomposed into common constituent domains derived from a more limited repertoire of ∼15,000 superfamilies [19].

What is protein domain family?

Protein domains are the common currency of protein structure and function. Over 10,000 such protein families have now been collected in the Pfam database. ... It can be shown that this protein family has its origins in basic animals such as the poriferan sponges where it is found in cell-surface-receptor proteins.

How does phosphorylation of a protein affect its activity?

Phosphorylation regulates protein function and cell signaling by causing conformational changes in the phosphorylated protein. ... First, conformational changes regulate the catalytic activity of the protein. Thus, a protein can be either activated or inactivated by phosphorylation.

What is a protein family quizlet?

Protein family. Protein family = similar, but not identical proteins within an organism. Proteins within a family have similar AA sequences, and therefore, similar (but generally not identical) structure and function. Protein families are created by duplication(s) of an ancestral gene.
