Names and origin

Protein namesRecommended name:
Penicillopepsin
EC=3.4.23.20
Alternative name(s):
Peptidase A
OrganismPenicillium janthinellum (Penicillium vitale)
Taxonomic identifier5079 [NCBI]
Taxonomic lineageEukaryota › Fungi › Dikarya › Ascomycota › Pezizomycotina › Eurotiomycetes › Eurotiomycetidae › Eurotiales › Trichocomaceae › mitosporic Trichocomaceae › Penicillium

Protein attributes

Sequence length323 AA.
Sequence statusComplete.
Protein existenceEvidence at protein level

General annotation (Comments)

Catalytic activity

Hydrolysis of proteins with broad specificity similar to that of pepsin A, preferring hydrophobic residues at P1 and P1', but also cleaving 20-Gly-|-Glu-21 in the B chain of insulin. Clots milk, and activates trypsinogen.

Sequence similarities

Belongs to the peptidase A1 family.

Caution

The sequence shown is derived from the best amino acid sequence data as modified by the X-ray data.
