PROSITE documentation PDOC00355Small hydrophilic plant seed proteins signature
The following small hydrophilic plant seed proteins are structurally related:
- Arabidopsis thaliana proteins GEA1 and GEA6.
- Cotton late embryogenesis abundant (LEA) protein D-19.
- Carrot EMB-1 protein.
- Barley LEA proteins B19.1A, B19.1B, B19.3 and B19.4.
- Maize late embryogenesis abundant protein Emb564.
- Radish late seed maturation protein p8B6.
- Rice embryonic abundant protein Emp1.
- Sunflower 10 Kd late embryogenesis abundant protein (DS10).
- Wheat Em proteins.
These proteins contains from 83 to 153 amino acid residues and may play a role [1,2] in equipping the seed for survival, maintaining a minimal level of hydration in the dry organism and preventing the denaturation of cytoplasmic components. They may also play a role during imbibition by controlling water uptake.
As a signature pattern, we selected the best conserved region in the sequence of these proteins, it is a glycine-rich nonapeptide located in the N-terminal section.
