A nonacosapeptide corresponding to the N-terminal sequence 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
通过常规溶液法合成了与小鼠金属硫蛋白I的N端序列1-29(β片段)相对应的非糖肽和相关肽,并研究了它们与重金属(Cu2 +,Cu +和Cd2 +)的结合特性。到目前为止,与N. crassa MT和A. bisporus MT的情况一样,各种肽的Cu(2 +)-或Cu(+)结合活性并不很大地依赖于肽结构。相反,这些肽的Cd(2+)结合活性是相当结构依赖性的。
