NE-monomethyl-lysine, NG-NG'-dimethyl-arginine, and NG-NG-dimethyl-arginine from tooth protein fractions were identified utilizing thin-layer chromatography, amino acid analysis, and gas chromatography. It is suggested that a relationship exists between the presence of these N-methylated basic amino acids and the resting stage of tooth tissue.
利用薄层色谱法、氨基酸分析法和气相色谱法,从牙齿蛋白质组分中鉴定出了N-单甲基赖氨酸、NG-NG'-二甲基精氨酸和NG-NG-二甲基精氨酸。有人提出,这些N-甲基化碱性氨基酸的存在与牙齿组织的静止期之间存在关联。
