title: [Expression of a bacterial gene, cloned in the yeast, Saccharomyces cerevisiae].
abstract: Vectors allowing cloning of foreign D.N.A. in the yeast Saccharomyces cerevisiae have been recently described. We have introduced in this yeast the lac Z gene of the bacteria Escherichia coli. An active beta-galactosidase, which is absent in the recipient strain, has been detected in transformed yeast. We thus conclude that the bacterial lac Z gene is expressed in yeast. We further showed that the enzyme found in the transformed yeast is identical to the bacterial enzyme with respect to size and immunological criteria.
