Lineage for Protein: Hypothetical protein AF0060

1. Root: SCOP 1.73

2. Class a: All alpha proteins [46456] (258 folds)

3. Fold a.204: all-alpha NTP pyrophosphatases [101385] (1 superfamily) multihelical: dimeric 4-helical bundle surrounded by other helices; oligomerizes further in a tetramer

4. Superfamily a.204.1: all-alpha NTP pyrophosphatases [101386] (4 families) basic module consist of 5 active site-forming helices; four from one subunit/structural repeat; the fifth from the other subunit/repeat

5. Family a.204.1.3: AF0060-like [140794] (1 protein) consists of a single member with an orphan sequence; "circular permutation" of putative active site residues: the catalytic lysine resides in the N-terminal helix instead of the missing in this family C-terminal helix; probable biological unit is a tertramer, distinct from the MazG family tetramer

6. Protein Hypothetical protein AF0060 [140795] (1 species)
