The researchers propose that their system, comprised of a protein capsid and a matching arginine tagged target enzyme, is a viable method of regulating enzyme activity within a cell. Their design is simple and easily applicable to other proteins.
Once again, research has yielded many useful applications for this system as it pushes us further towards cell activity control. Think of containing and regulating tumor growth, viral dependent enzymes and others. As the researchers admit, it still needs a lot of work but these preliminary results are promising.
