• Spontaneous cyclization of a chain shortened lysine analog
  作者：S Ranganathan、D Ranganathan、W.P Singh

  DOI：10.1016/0040-4039(88)85099-8

  日期：1988.1

  The chain shortened analog of lysine, H2NCH2CH2CH(NHZ)COOR, generated from N-protected glutamine esters, undergoes spontaneous cyclization. The results show that amino acids having H2NCH2CH2 - side chains cannot be supported on tRNA and provides a rationale for keeping the amino group of lysine by as many as four méthylènes away from the peptide backbone.

  由N保护的谷氨酰胺酯生成的赖氨酸链缩短的类似物H 2 NCH 2 CH 2 CH（NHZ）COOR进行自发环化。结果表明，具有H 2 NCH 2 CH 2-侧链的氨基酸不能在tRNA上得到支持，并且为将赖氨酸的氨基与肽主链保持多达四个甲硫基的氨基酸提供了原理。
