Addtional InformationFUNCTION:Serine protease. Has a substrate preference for the hydrophobic residues Phe and Ala and the basic residue Asp in the P1 position, and for Asp, Leu or Ala in the P1' position.ENZYME REGULATION:Activated by calcium. Inhibited by the serine protease inhibitors 4-(2-aminoethyl)benzenesulphonyl fluoride (AEBSF), PMSF, di-isopropyl phosphofluoridate (DFP) and soybean trypsin inhibitor (SBTI). Not inhibited by benzamidine or iodoacetamide. Leupeptin and pepstatin A have a minor inhibitory action.BIOPHYSICOCHEMICAL PROPERTIES:pH dependence: Optimum pH is 5.0; Temperature dependence: Optimum temperature is 80 degrees Celsius. Thermostable;TISSUE SPECIFICITY:Expressed in immature siliques and at lower levels in stems and flowers.DEVELOPMENTAL STAGE:Highest levels of expression detected during silique development.MASS SPECTROMETRY:Mass=76102.8; Method=MALDI; Range=107-757; Source=PubMed:12413398;SIMILARITY:Belongs to the peptidase S8 family.
