Experimental Records
RECORD: Rec_0337756 VERIFIED: YES
Provenance & Taxonomy
not reported [other]
Structure & Mods
linear peptide [Linear]
canonical L-amino-acid peptide [L]
Bio-Activity Profile
-
Escherichia coli TOP10
Mex pooled growth assay (OD_ID at 4.5 h; Wald adjusted p-value)
RECORD: Rec_0361219 VERIFIED: YES
Provenance & Taxonomy
Paenibacillus polymyxa var [Bacterium]
Structure & Mods
head-to-tail cyclic peptide [Cyclic]
mixed L/D amino-acid peptide [Mixed]
Lipidation
Warning: the sequence is a close mimic of the natural peptide antibiotic. In the natural form, there are multiple Dab (2,4-diaminobutanoic acid), which are represented here as lysines. The molecule is cyclic due to the formation of an amide bond between the amino group of Dab in position 4 and the carboxyl group of the C-terminus. Residue Leu6 is a D-amino acid and the N-terminus is attached by a fatty acid (Polymyxin E1= colistin A: fatty acid A=6-methyloctanoic acid; Polymyxin E2=colistin B: fatty acid B=6-methylheptanoic acid)
