Lineage for Species: Mycobacterium smegmatis [TaxId: 1772]

1. Root: SCOPe 2.01

2. Class d: Alpha and beta proteins (a+b) [53931] (376 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] (23 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.3.1.5: Arylamine N-acetyltransferase [54047] (2 proteins) fold similar to that of the factor XIII catalytic domain

6. Protein automated matches [190090] (3 species) not a true protein

7. Species Mycobacterium smegmatis [TaxId:1772] [186812] (1 PDB entry)
