CC -!- FUNCTION: Cysteine protease that cleaves specifically after arginine or CC lysine residues. Does not cleave caspase-specific substrates. Required CC for proteolytic processing of GRI (PubMed:25398910). CC {ECO:0000269|PubMed:25398910}. CC -!- ACTIVITY REGULATION: Inhibited by serpin ZX and nitric oxide through CC cysteine nitrosylation. {ECO:0000269|PubMed:17028019, CC ECO:0000269|PubMed:17110382}. CC -!- SUBCELLULAR LOCATION: Secreted, extracellular space, apoplast CC {ECO:0000269|PubMed:17028019}. CC -!- TISSUE SPECIFICITY: Expressed in root tips, cauline leaves, flowers and CC siliques. {ECO:0000269|PubMed:17028019, ECO:0000269|PubMed:21395887}. CC -!- PTM: The two subunits are derived from the precursor sequence by an CC autocatalytic mechanism. CC -!- PTM: S-nitrosylation at Cys-147 suppresses both autoprocessing and CC proteolytic activity of the full-length protein, but does not affect CC the activity of the mature processed form. CC {ECO:0000269|PubMed:17110382}. CC -!- SIMILARITY: Belongs to the peptidase C14B family. {ECO:0000305}.
