Lineage for Family c.8.2.3: AF0055-like

1. Root: SCOPe 2.01

2. Class c: Alpha and beta proteins (a/b) [51349] (147 folds)

3. Fold c.8: The "swivelling" beta/beta/alpha domain [52008] (10 superfamilies) 3 layers: b/b/a; the central sheet is parallel, and the other one is antiparallel; there are some variations in topology this domain is thought to be mobile in most multi-domain proteins known to contain it

4. Superfamily c.8.2: LeuD/IlvD-like [52016] (4 families) contains mixed beta-sheet barrel, closed n=7, S=10

5. Family c.8.2.3: AF0055-like [141979] (1 protein) PF01989; DUF126; probable link between the LeuD-like and Phosphohistidine domain superfamilies (sequence similarity crosshits)
