WebbThermolysin preferentially cleaves at the N-terminus of the hydrophobic residues leucine, phenylalanine, valine, isoleucine, alanine and methionine. The optimal digestion temperature range is 65–85°C. Thermolysin activity is optimal at pH 5.0–8.5. Applications Peptide mapping Protein identification WebbBased on previous works, thermolysin appears therefore as a protease of choice, which cannot access the IEM or stroma. After proteolytic digestion of surface proteins, intact chloroplasts were re-isolated on a Percoll cushion, and chloroplast sub-compartment (envelope, stroma, thylakoids) were fractionated. WebbThermolysin is a thermostable metalloproteinase. The high digestion temperatures may be used as an alternative to denaturants to improve digestion of proteolytically resistant proteins.
