The model peptide synthesis from mixtures of amino acids was carried out under the thermal cycling and isothermal modes. The compositions of the obtained mixtures of products and the primary amino acid sequence of the synthesized peptides were determined by Fourier transform ion cyclotron resonance mass spectrometry and tandem mass spectrometry in combination with high-performance liquid chromatography
氨基酸混合物的模型肽合成在热循环和等温模式下进行。通过傅里叶变换离子回旋共振质谱和串联质谱结合高效液相色谱法,应用合成肽的从头测序,确定了所得产物混合物的组成和合成肽的一级氨基酸序列。产品。与可能的统计组相比,肽的天然合成过程显示在相对温和的温度条件下发生并且产生的肽数量显着减少。系统的演变发生在固相合成过程中,一系列最不稳定的肽消失了。
