Da. Williamson et Dr. Benson, REMARKABLE HELIX STABILIZATION VIA EDGE-TO-FACE TRYPTOPHAN-PORPHYRIN INTERACTIONS IN A PEPTIDE-SANDWICHED MESOHEME, Chemical communications, (9), 1998, pp. 961-962
Tryptophan residues in a peptide-sandwiched mesoheme provide helix sta
bilization via edge-to-face interactions between the Trp indole side-c
hains and the porphyrin ring.
