Protease ID39, scientifically assigned with the Enzyme Commission (E.C.) number 3.4.22.-, is a C40 family peptidase, yet to be classified under a specific subgroup, isolated from Labilibacter marinus.

The enzyme, produced recombinantly and purified from Escherichia coli, belongs to the cysteine-type peptidase category, playing a vital role in the specific degradation of the cell wall of Chlorella vulgaris. Chlorella vulgaris is a unicellular, green microalga extensively employed in various applications, such as a dietary supplement and a protein-dense food/feed additive due to its rich nutritional profile.

The efficacious application of Protease ID39 in the degradation of its cell wall underscores the enzyme’s potential in facilitating the extraction of intracellular contents, which can be pivotal for nutritional and biochemical applications.

Protease ID39 is supplied in a solution containing 35 mM NaHepes buffer (pH 7.5), 750 mM NaCl, 200 mM Imidazole, 3.5 mM CaCl2, and 25% (v/v) glycerol, at a concentration of 1 mg/mL.
