Synthesis of two heptapeptides corresponding to sequences 50-56 and 90-96 of adrenodoxin from bovine adrenal cortex and formation of their iron-sulfur complexes.

Abstract
Two heptapeptides, Z-Leu-Ala-Cys (Bzl)-Ser-Thr-Cys (Bzl)-His-OH (A) and Z-Leu-Gly-Cys (Bzl)-Gln-Ile-Cys (Bzl)-Leu-OH (B), corresponding to sequences 50-56 and 90-96 of adrenodoxin from bovine adrenal cortex, respectively, were synthesized. The deblocked peptides from A and B formed iron-sulfur complexes, both of which gave absorption maxima at 415 nm.
