This is the catalytic domain of of cysteine peptidases from C54 family, which includes cysteine protease ATG4 from human and its homologues from fungi and plants. ATG4 plays a key role in cytoplasm to vacuole transport (Cvt) and autophagy by mediating both proteolytic activation and delipidation of ATG8 [1-3].	Domain
