Class d: Alpha and beta proteins (a+b) [53931] (376 folds) |
Fold d.3: Cysteine proteinases [54000] (1 superfamily) consists of one alpha-helix and 4 strands of antiparallel beta-sheet and contains the catalytic triad Cys-His-Asn |
d.3.1.1: Papain-like [54002] (26 proteins) |
d.3.1.2: FMDV leader protease [54037] (1 protein) |
d.3.1.3: Calpain large subunit, catalytic domain (domain II) [54040] (1 protein) |
d.3.1.4: Transglutaminase core [54044] (3 proteins) |
d.3.1.5: Arylamine N-acetyltransferase [54047] (2 proteins) fold similar to that of the factor XIII catalytic domain |
d.3.1.6: Ubiquitin carboxyl-terminal hydrolase UCH-L [54050] (3 proteins) |
d.3.1.7: Adenain-like [54054] (6 proteins) Pfam PF02902; Ulp1 protease family |
d.3.1.8: Microbial transglutaminase [75336] (1 protein) inverted positions of the catalytic triad Asp and His residues |
d.3.1.9: Ubiquitin carboxyl-terminal hydrolase, UCH [82568] (6 proteins) Pfam PF00443 |
d.3.1.10: Avirulence protein Avrpph3 [102723] (1 protein) |
d.3.1.11: Ubiquitin thiolesterase protein OTUB2 (Otubain-2) [110773] (1 protein) probably the same as Pfam PF02338, OTU-like cysteine protease, but 1TFF (Uniprot Q96DC9) was not detected by the Pfam model |
d.3.1.12: IgG-specific endopeptidase IdeS (Sib38) [117762] (1 protein) |
d.3.1.13: Lpg0564-like [142864] (1 protein) Pfam PF07313, DUF1460; contains new PDB entry 2p1g, annotated as putative xylanase |
d.3.1.14: Phytochelatin synthase [142867] (1 protein) Pfam PF05023; assosiated Pfam PF09328 (DUF1984) is a part of the same functional unit |
d.3.1.15: CHAP domain [142870] (1 protein) Pfam PF05257 |

d.3.1.21: YiiX-like [159855] (1 protein) Pfam PF06520; DUF1105; circularly permuted active site residues compare to papain |
d.3.1.22: Autophagin-like [159858] (3 proteins) Pfam PF03416 |
d.3.1.0: automated matches [191342] (1 protein) not a true family |
