摘要
The first chemical synthesis of nuclear protein HMGAla via Ser/Thr ligation is reported. Notably, Hmb (2-hydroxy-4-methoxybenzyl) exhibits crucial improvement of both the difficult coupling during solid phase peptide synthesis and the poor ligation encountered in protein synthesis. These efforts led to preparation of HMGAla analogs with well-defined phosphorylation and methylation patterns (9 synthetic proteins in total), thus overcoming the heterogeneous and 1) combinatory problems inherent to protein post-translational modifications (PTMs), and facilitating the study of the regulatory roles of such PTMs.
