Class b: All beta proteins [48724] (180 folds) |
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 |
Superfamily b.34.13: Chromo domain-like [54160] (4 families) SH3-like barrel is capped by a C-terminal helix |
Family 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 |
Protein Heterochromatin protein 1, HP1 [54166] (4 species) duplication: consists of two homologous domains, N-terminal chromo domain and C-terminal chromo shadow domain |
