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.
合成了两个七肽,Z-Leu-Ala-Cys (Bzl)-Ser-Thr-Cys (Bzl)-His-OH (A) 和 Z-Leu-Gly-Cys (Bzl)-Gln-Ile-Cys (Bzl)-Leu-OH (B),分别对应牛肾上腺皮质中的类
固醇酶(adrenodoxin)序列50-56和90-96。A和B中的去保护肽形成了
铁硫复合物,二者的吸收峰值均在415 nm。
