Staphylococcus aureus V8 protease (Endoproteinase Glu-C) belongs to the serine protease family and can specifically hydrolyze carboxy-terminal peptide bonds of glutamic acid (Glu) or aspartate (Asp) residues. Its specificity is directly affected by the composition of the buffer, recognizing and cutting Glu carboxy-terminal peptide bonds in NH4HCO3 of pH7.8 and CH3COONH4 of pH4.0, recognizing and cutting Glu or Asp carboxy-terminal peptide bonds in phosphate buffers of pH7.8，but the hydrolysis rate of Glu was higher than that of Asp. Glu-C has been reported to be active in 0.2% SDS (sodium lauryl sulfate) and 4.0M urea.
To get the most use out the enzyme, resuspend the enzyme in 500 μl H2O and aliquot 50 ul each in 10 tubes.
Store at -25 ~ -15℃ for 2 years
