SCOPe 2.03: Superfamily b.34.13: Chromo domain-like

Lineage for Superfamily b.34.13: Chromo domain-like

1. Root: SCOPe 2.03

2. Class b: All beta proteins [48724] (174 folds)

3. Fold b.34: SH3-like barrel [50036] (21 superfamilies)
   barrel, partly opened; n*=4, S*=8; meander
   the last strand is interrupted by a turn of 3-10 helix

4. Superfamily b.34.13: Chromo domain-like [54160] (4 families)
   SH3-like barrel is capped by a C-terminal helix

Families:

1. b.34.13.1: "Histone-like" proteins from archaea [54161] (2 proteins)

2. b.34.13.2: Chromo domain [54165] (8 proteins)
   lacks the SH3-like barrel first strand that can be complemented by bound peptide ligand; in shadow chromo domain the corresponding site is altered by insertion; similarity to the IL8-like fold

3. b.34.13.3: Chromo barrel domain [117157] (4 proteins)
   typical SH3-like barrel fold; similar sequence motif to the canonical chromo domain

4. b.34.13.0: automated matches [191621] (1 protein)
   not a true family
