| Description: | Barwin is a basic protein isolated from aqueous extracts of barley seeds. It is 125 amino acids in length, and contains six cysteine residues that combine to form three disulphide bridges [, ]. Comparative analysis shows the sequence to be highly similar to a 122 amino acid stretch in the C-terminal of the products of two wound-induced genes (win1 and win2) from potato, the product of the hevein gene of rubber trees, and pathogenesis-related protein 4 from tobacco. The high levels of similarity to these proteins, and their ability to bind saccharides, suggest that the barwin domain may be involved in a common defence mechanism in plants. | Short Name: | Barwin_CS |
