Lineage for Family b.34.6.3: Rv2302-like

1. Root: SCOP 1.73

2. Class b: All beta proteins [48724] (165 folds)

3. Fold b.34: SH3-like barrel [50036] (18 superfamilies) barrel, partly opened; n*=4, S*=8; meander the last strand is interrupted by a turn of 3-10 helix

4. Superfamily b.34.6: Cell growth inhibitor/plasmid maintenance toxic component [50118] (3 families) contains insert beta-sheet subdomain and C-terminal helix

5. Family b.34.6.3: Rv2302-like [141248] (1 protein) different orientation for the extra C-terminal helix relative the SH3-like barrel
