title: Cloning and DNA sequence analysis of the serC-aroA operon from Salmonella gallinarum; evolutionary relationships between the prokaryotic and eukaryotic aroA-encoded enzymes.
abstract: The serC-aroA operon of Salmonella gallinarum was isolated from a gene library using a labelled oligonucleotide probe and by complementation of an aroA Escherichia coli strain. The nucleotide sequence of a 2.6 kbp fragment was determined. The predicted amino acid sequence of the aroA gene product was compared to the equivalent sequence from ten other organisms. Computer-generated evolutionary trees clearly divide the eleven sequences into four different groups: Gram-negative bacteria, Gram-positive bacteria, fungi and plants. These trees depict a close evolutionary relationship between the sequences from Gram-negative bacteria and higher plants.
