SCOPe 2.07: Domain d2ec5b3: 2ec5 B:1094-1285

Lineage for d2ec5b3 (2ec5 B:1094-1285)

1. Root: SCOPe 2.07

2. Class d: Alpha and beta proteins (a+b) [53931] (388 folds)

3. 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

4. Superfamily d.3.1: Cysteine proteinases [54001] (24 families)
   the constitute families differ by insertion into and circular permutation of the common catalytic core made of one alpha-helix and 3-strands of beta-sheet

5. Family d.3.1.17: PMT C-terminal domain like [159843] (1 protein)
   displays a minimal thiol-protease fold and its catalytic triad; potential redox regulation: the catalytic cysteine can form a disulfide bond with an N-terminal cysteine

6. Protein Dermonecrotic toxin, ToxA [159844] (1 species)
   Synonym: Mitogenic toxin PMT

7. Species Pasteurella multocida [TaxId:747] [159845] (3 PDB entries)
   Uniprot P17452 1094-1285

8. Domain d2ec5b3: 2ec5 B:1094-1285 [146783]
   Other proteins in same PDB: d2ec5a1, d2ec5a2, d2ec5b1, d2ec5b2
   automated match to d2ec5a3
