title: Measurement of translational accuracy in vivo: missense reporting using inactive enzyme mutants.
abstract: The measurement and potential technological significance of in vivo missense errors are briefly reviewed. A recently developed approach is described in which reporter enzyme activity is generated by mistranslation of a gene coding for an inactive mutant form of the enzyme. Initial results obtained using the alpha subunit of E coli tryptophan synthetase and bacterial luciferase are discussed, as well as the prospects for further development of this method.
