Lineage for Species: Mycobacterium tuberculosis

1. Root: SCOPe 2.08

2. Class d: Alpha and beta proteins (a+b) [53931] (396 folds)

3. Fold d.96: T-fold [55619] (2 superfamilies) beta(2)-alpha(2)-beta(2); 2 layers: alpha/beta; antiparallel sheet 1234 tunnel-shaped: its known members form wide oligomeric barrels different sizes

4. Superfamily d.96.1: Tetrahydrobiopterin biosynthesis enzymes-like [55620] (5 families) bind purine or pterin in topologically similar sites between subunits

5. Family d.96.1.3: DHN aldolase/epimerase [55628] (3 proteins) beta-sheets of four subunits form a barrel, closed: n=16, S=16 automatically mapped to Pfam PF02152

6. Protein automated matches [310846] (1 species) not a true protein

7. Species Mycobacterium tuberculosis [311175] (1 PDB entry)
