Abstract
Tryptophan residues in a peptide-sandwiched mesoheme provide helix stabilization via edge-to-face interactions between the Trp indole side-chains and the porphyrin ring.

from the analogue by altering the point of attachment between one
propionate group and the heme ring followed by energy minimization.
