Experimental Records
RECORD: Rec_0280228 VERIFIED: YES
Provenance & Taxonomy
synthetic construct [Synthetic]
Cathelicidin
32630
Structure & Mods
lysine-tethered side-chain stapled peptide [Cyclic]
noncanonical stereochemical modification [Modified]
None
Amidation
The Ⓚ (position: 6 and 10) in sequence indicates Nε-o-Ns-Nα-Fmoc-lysine before stapling. Ⓚ (6) and Ⓚ (10) are cross-linked by a but-2-ynyl spacer employing the N-alkylation reaction
