Addtional InformationIt contains four disulfide bonds:5,47; 16,36; 22,43; 26,45. Active against E. coli, P. aeruginosa, and E. hirae. 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. ; Fabatin-2 differs from fabatin-1 by only 1 amino acid at position 13, N in fabatin-2, H in fabatin-1., Synthesis Type: Ribosomal; 95% Inhibition against Lactobacillus brevis at 10.3 ¼g/ml; 95% Inhibition against Pediococcus dextrinicus at 11.2 ¼g/ml; 95% Inhibition against Staphylococcus aureus Newman at >45 ¼g/ml; 95% Inhibition against Bacillus cereus at >45 ¼g/ml; 95% Inhibition against at Salmonella typhimurium >45 ¼g/ml; 95% Inhibition against at Escherichia coli >45 ¼g/ml; 95% Inhibition against Pseudomonas aeruginosa at 10.3 ¼g/ml
