CC -!- FUNCTION: Asparagine-specific endopeptidase that may be involved in
CC processing of proteins targeted to vacuoles. Cysteine protease required
CC for post-translational proteolysis of seed storage proteins in the
CC protein storage vacuole (PSV) of developing seeds, by processing of
CC proglutelin precursor to mature glutelin subunits, thus contributing to
CC the formation of protein crystalline structures in PSV (Ref.1,
CC PubMed:19154227, PubMed:19933265). {ECO:0000269|PubMed:19154227,
CC ECO:0000269|PubMed:19933265, ECO:0000269|Ref.1}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of proteins and small molecule substrates at
CC -Asn-|-Xaa- bonds.; EC=3.4.22.34;
CC Evidence={ECO:0000269|PubMed:19154227};
CC -!- SUBCELLULAR LOCATION: Protein storage vacuole
CC {ECO:0000269|PubMed:19154227}.
CC -!- TISSUE SPECIFICITY: Expressed in developing seeds.
CC {ECO:0000269|PubMed:19933265}.
CC -!- PTM: Auto-catalytic activation. {ECO:0000269|PubMed:19154227}.
CC -!- DISRUPTION PHENOTYPE: In PAK22, higher quantities of 57 kDa
CC polypeptides and lower levels of 40 kDa acidic and 20 kDa basic
CC glutelin subunits in seeds due to reduced vacuolar processing enzyme
CC (VPE) activity and leading to non-crystalline lattice structure of
CC protein storage vacuoles (PSVs). Seedlings growth retardation.
CC {ECO:0000269|PubMed:19933265, ECO:0000269|Ref.1}.
CC -!- SIMILARITY: Belongs to the peptidase C13 family. {ECO:0000305}.
