Experimental Records
RECORD: Rec_0404561 VERIFIED: YES
Provenance & Taxonomy
synthetic construct [Synthetic]
Thanatin
32630
Structure & Mods
linear peptide [Linear]
all-D amino-acid peptide [D]
Amidation
11-18
D-thanatin (all D-amino acids) showed similar activity against multiple Gram+ and fungi strains, but became much less active against Gram- bacteria, indicating some chiral configuration is needed (non-membranes?)
