Lineage for Species: Escherichia coli [TaxId: 562]

1. Root: SCOPe 2.08

2. Class e: Multi-domain proteins (alpha and beta) [56572] (74 folds)

3. Fold e.8: DNA/RNA polymerases [56671] (1 superfamily) divided into morphological domains including "palm", "thumb" and "fingers"; the catalytic "palm" domain is conserved to all members

4. Superfamily e.8.1: DNA/RNA polymerases [56672] (9 families) "palm" domain has a ferredoxin-like fold, related to that of an adenylyl cyclase domain

5. Family e.8.1.1: DNA polymerase I [56673] (5 proteins) in the multi-domain class (e), this applies to domains with different numbers of (sub)domains than the most common domain

6. Protein Family B DNA polymerase [56680] (7 species)

7. Species Escherichia coli [TaxId:562] [103399] (1 PDB entry)
