Sumario: | Proteins are involved in practically every single biological process. The many enzymes involved in their synthesis, cleavage, and posttranslational modification (PTM) carry out highly specific tasks with no usage of protecting groups. Yet, the chemists’ strategy of protection/deprotection potentially can be highly useful, for example, when a specific biochemical reaction catalyzed by a broad‐specificity enzyme needs to be inhibited, during infection of cells by enveloped viruses, in the invasion and spread of cancer cells, and upon mechanistic investigation of signal‐transduction pathways. Doing so requires highly specific binding of peptide substrates in aqueous solution with biologically competitive affinities. Recent development of peptide‐imprinted cross‐linked micelles allows such protection and affords previously impossible ways of manipulating peptides and proteins in enzymatic transformations. |
