Amino acids and peptides. XIII. Synthesis of a nonacosapeptide corresponding to the N-terminal sequence 1-29 (.BETA.-fragment) of human liver metallothionein II (hMT II) and its heavy metal-binding properties.
摘要:
通过叠氮偶联五种肽段[1、2、4、6和8],然后进行高频脱保护,合成了对应于人肝金属硫蛋白II(hMT II)N端序列1-29(β-片段)的非酰肽,并考察了其重金属结合特性。结果表明,与 hMT II C 端序列 30-61 相应的合成 β 片段和合成 α 片段的镉结合能力强于原生大鼠硫蛋白。此外,研究还发现α-片段和β-片段都优先与铜离子而不是镉离子结合。

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
