General annotation (Comments)

Function

Thiol protease. Has dipeptidylpeptidase activity. Can act as both an exopeptidase and endopeptidase By similarity.

Catalytic activity

Release of an N-terminal dipeptide, Xaa-Yaa-|-Zaa-, except when Xaa is Arg or Lys, or Yaa or Zaa is Pro.

Cofactor

Binds 1 chloride ion per heavy chain By similarity.

Subunit structure

Tetramer of heterotrimers consisting of exclusion domain, heavy- and light chains By similarity.

Subcellular location

Lysosome By similarity.

Post-translational modification

The N-terminus of the heavy chain is heterogeneously processed to produce four different chains.

Sequence similarities

Belongs to the peptidase C1 family.

Biophysicochemical properties

pH dependence:

Optimum pH is 6.5. Active over a broad pH range.
