| Abstract: | The structural gene for citrate synthase of Acinetobacter anitratum has been cloned in Escherichia coli in a form which expresses the enzyme. A library of EcoRI fragments of Acinetobacter genomic DNA was prepared in the vector lambda gt10, and clones were screened by hybridization with an E. coli citrate synthase clone under conditions of reduced stringency. A 6.5 kbp clone was obtained which was subcloned into pBR322, and shown to direct the formation of Acinetobacter citrate synthase in E. coli hosts. The promoter was located within a BglII fragment, and from this information the orientation of the gene was deduced. |
