title: Identification of the ftsA gene product.
abstract: A nonsense mutation was identified in the essential cell division gene ftsA of Escherichia coli. A gamma-transducing phage was isolated which complemented this mutation. This phage programmed the synthesis of four bacterial proteins in UV-irradiated cells. By substituting the nonsense mutation for the ftsA+ allele in this transducing phage and comparing the proteins programmed by it in UV-treated Su+ and Su- cells, the product of the ftsA gene was identified as a protein with a molecular weight of 50,000.
