Lineage for Family a.204.1.1: Type II deoxyuridine triphosphatase

1. Root: SCOPe 2.07

2. Class a: All alpha proteins [46456] (289 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] (5 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.204.1.1: Type II deoxyuridine triphosphatase [101387] (1 protein) one subunit comprises two degenerate structural repeats, organised into the "rigid" and "mobile" subdomains
