EC Number | 3.4.14.10 |
Enzyme Function | FUNCTION: Component of the proteolytic cascade acting downstream of the 26S proteasome in the ubiquitin-proteasome pathway (By similarity). Efficiently cleaves Ala-Ala-Ala-polypeptide and Pro-Pro-Ala-polypeptide, Val-Leu-Lys-polypeptide only at high concentration. Does not cleave Ala-Phe-Pro-polypeptide nor Pro-Leu-Gly-polypeptide. {ECO:0000250}. |
