Amino Acids and Peptides. XXXV. Synthesis of Mouse Metallothionein I.(2). Synthesis of a Nonacosapeptide Corresponding to N-Terminal Sequence 1-29(.BETA.-Fragment) of Mouse Metallothionein I and Related Petides and Examination of Their Heavy Metal-Binding Properties.
A nonacosapeptide corresponding to the N-terminalsequence 1-29 (beta-fragment) of mouse metallothionein I and related peptides were synthesized by the conventional solution method and their heavy metals (Cu2+, Cu+ and Cd2+)-binding properties were examined. The Cu(2+)- or Cu(+)-binding activities of various peptides were not greatly dependent on the peptide structure, so far as examined, as in the
