2018, BiomaterialsCitation Excerpt :Recently, sortase A was optimized by mutation and screening to enhance reaction efficiency by tuning reaction equilibrium [205]. In addition, some rare sites on proteins can be explored for site-selective modification, such as glycan chains on antibodies [206] and some low-abundance amino acids like methionine [42] and tryptophan [207]. Much progress has been made in the “grafting from” method in the past decade, but it is still challenging to directly grow a polymer from a specific site on a protein in a more biocompatible, efficient and controlled manner.
