| Addtional Information | Mature peptide: 1-47, Fabatin-1 differs from fabatin-2 by only 1 amino acid at position 13, H in fabatin-1, N in fabatin-2, It contains four disulfide bonds:5,47; 16,36; 22,43; 26,45. Active against E. coli, P. aeruginosa, and E. hirae. Note that the material used for antimicrobial activity assays contains both fabatin-1 and fabatin-2, which differ only at residue 13, N for fabatin-1 and H for fabatin-2. It's unclear whether these two very closely related fabatins differ in antimicrobial activity. Updated 12/2017. |
