Abstract
 |
Crystallins are the dominant structural components of the eye lens. Among the
different type of crystallins, the beta and gamma crystallins form a family of
related proteins [1, 2]. Structurally, beta and gamma crystallins
are composed of two similar domains which, in turn, are each composed of two similar
motifs with the two domains connected by a short connecting peptide. Each motif,
which is about forty amino acid residues long, is folded in a distinctive
'Greek key' pattern. |

- P02966 DESS_MYXXA: A calcium-binding protein from the sporulating bacterium Myxococcus xanthusa forms a major part of the spore coat
- P46058 EDSP_CYNPY
- P09353 SR3A_PHYPO: Spherulin 3a from the slime mold Physarum polycephalum. Spherulin 3a is a development specific protein synthesized in response to various kinds of stress leading to encystment and dormancy. The sequence of Spherulin 3a consists of two 'Greek key' motifs [3]
