Lineage for Superfamily b.34.13: Chromo domain-like

  1. Root: SCOP 1.75B
  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) (S)
    SH3-like barrel is capped by a C-terminal helix

Families:

  1. b.34.13.1: "Histone-like" proteins from archaea [54161] (2 protein domains)
  2. b.34.13.2: Chromo domain [54165] (8 protein domains)
    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 protein domains)
    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
