FunFam 28: S9 family peptidase

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 5 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Dipeptidyl-peptidase activity GO:0008239
Catalysis of the hydrolysis of N-terminal dipeptides from a polypeptide chain.
2 B2RIT0 (/IDA) C3J8X2 (/IDA)
Peptide binding GO:0042277
Interacting selectively and non-covalently with peptides, any of a group of organic compounds comprising two or more amino acids linked by peptide bonds.
2 B2RIT0 (/IDA) C3J8X2 (/IDA)
Peptidase activity GO:0008233
Catalysis of the hydrolysis of a peptide bond. A peptide bond is a covalent bond formed when the carbon atom from the carboxyl group of one amino acid shares electrons with the nitrogen atom from the amino group of a second amino acid.
1 P0C959 (/IDA)
Peptidase activity GO:0008233
Catalysis of the hydrolysis of a peptide bond. A peptide bond is a covalent bond formed when the carbon atom from the carboxyl group of one amino acid shares electrons with the nitrogen atom from the amino group of a second amino acid.
1 Q8EEY6 (/ISS)
Protein homodimerization activity GO:0042803
Interacting selectively and non-covalently with an identical protein to form a homodimer.
1 B2RIT0 (/IDA)

There are 2 GO terms relating to "biological process"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Peptide catabolic process GO:0043171
The chemical reactions and pathways resulting in the breakdown of peptides, compounds of 2 or more (but usually less than 100) amino acids where the alpha carboxyl group of one is bound to the alpha amino group of another.
2 B2RIT0 (/IDA) C3J8X2 (/IDA)
Proteolysis GO:0006508
The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.
1 Q8EEY6 (/ISS)

There are 4 GO terms relating to "cellular component"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Extracellular region GO:0005576
The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
1 Q2URT4 (/IDA)
Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
1 Q9P778 (/HDA)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
1 Q9P778 (/HDA)
Periplasmic space GO:0042597
The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria).
