Amino acids and peptides. XXVI. Synthesis of Agaricus bisporus metallothionein and related peptides and examination of their heavy metal-binding properties.
pentacosapeptide corresponding to the entire aminoacid sequence of Agaricus bisporus metallothionein (MT) and related cysteine-containing peptides were prepared by the conventional solution method and their heavy metal-binding properties were examined. The Cu2(+)- or Cu(+)-binding activities of various peptides were not greatly dependent on the peptide structure, so far as examined, although the pentacosapeptide
