Protein

Tricorn protease

Gene
tri, Ta1490
Organism
Thermoplasma acidophilum (strain ATCC 25905 / DSM 1728 / JCM 9062 / NBRC 15155 / AMRC-C165)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Tricorn degrades oligopeptides (probably derived from the proteasome) and channels the products to F1, F2 and F3 proteases, which then catalyze the terminal degradation step, yielding free amino acids.

pH dependencei

Optimum pH is 8.5-8.8.

Temperature dependencei

Optimum temperature is 65 degrees Celsius.
