SCOP 1.67: Domain d1yech1: 1yec H:1-113

Lineage for d1yech1 (1yec H:1-113)

1. Root: SCOP 1.67

2. Class b: All beta proteins [48724] (141 folds)

3. Fold b.1: Immunoglobulin-like beta-sandwich [48725] (22 superfamilies)
   sandwich; 7 strands in 2 sheets; greek-key
   some members of the fold have additional strands

4. Superfamily b.1.1: Immunoglobulin [48726] (4 families)

5. Family b.1.1.1: V set domains (antibody variable domain-like) [48727] (24 proteins)

6. Protein Immunoglobulin heavy chain variable domain, VH [88543] (20 species)
   VH domains of human and mouse antibodies are clustered by the sequence similarity within the germline encoded segment and then by the size of the complementarity determining regions CDR1 and CDR2, so the clusters may correspond to putative germline families in the species genomes; VH domains with artificial or grafted exogenous CDRs are listed as engineered species

7. Species Mouse (Mus musculus), cluster 3.2 [TaxId:10090] [88552] (141 PDB entries)

8. Domain d1yech1: 1yec H:1-113 [20145]
   Other proteins in same PDB: d1yech2, d1yecl1, d1yecl2
   part of Fab D2.3
   complexed with pnb, zn
