Lineage for Family c.1.28.2: Oxygen-independent coproporphyrinogen III oxidase HemN

1. Root: SCOPe 2.08

2. Class c: Alpha and beta proteins (a/b) [51349] (148 folds)

3. Fold c.1: TIM beta/alpha-barrel [51350] (34 superfamilies) contains parallel beta-sheet barrel, closed; n=8, S=8; strand order 12345678 the first seven superfamilies have similar phosphate-binding sites
