Analysis of a eukaryotic beta-galactosidase gene: the N-terminal end of the yeast Kluyveromyces lactis protein shows homology to the Escherichia coli lacZ gene product

The LAC4 gene of Kluyveromyces lactis, encoding the enzyme beta-galactosidase was mapped on a cloned DNA fragment and the sequence of the 5' end was determined. This sequence includes the 5' regulatory region involved in the induction by lactose and the N-terminal end of the protein coding...
