In vitro translation of messenger ribonucleic acid from sporulating and nonsporulating strains of Bacillus subtilis.

An in vitro protein-synthesizing system (rabbit reticulocyte) was programmed with total polyadenylated messenger ribonucleic acid from wild type and various mutants in the qa gene cluster of Neurospora crassa. The products of two of the qa genes, quinate dehydrogenase (qa-3+) and dehydroshikimate dehydratase (qa-4+), were identified by specific immunoprecipitation and sodium dodecyl sulfate-slab gel electrophoresis. The results indicated that for both genes induction of a specific enzyme activity by quinic acid depends on the de novo synthesis of a specific polypeptide and on the de novo appearance of specific messenger ribonucleic acid detectable by the in vitro translation assay. Furthermore, the results indicated that the appearance of this messenger ribonucleic acid is under the control of the qa-1 gene. The simplest interpretation of these results appears to be that induction of enzyme activity in the qa system is mediated by events at the transcriptional level.
