Glycine also enables efficient folding of a heterochiral EETI-II 2.5F analogue. LC–MS (total ion current vs time) monitoring for the oxidative protein folding of a heterochiral EETI-II 2.5F analogue possessing a scaffold core comprised of l-amino acids and a loop containing a stretch of five d-amino acids, one Gly, and two additional Gly substitutions. Charge-state series represent the major product (asterisks) at time zero, 2 min, and 16 h; observed masses represent monoisotopic masses.
