Eight kinds of cysteine-containing peptides related to human hepatic metallothionein were synthesized by conventional methods. The metal-binding properties of these peptides with Zn2+ and Cd2+ were indicated by an increase of ultraviolet absorbance resulting from mercaptide formation. The Cd-binding activities of various peptides obtained here were assessed by measuring the increase in absorbance of mercaptide at 250 nm as a function of the concentration of Cd. The binding abilities of the peptides with Cd differed substancially.
