Evolutionary events that generated the three regulatory isozymes of 3-deoxy-d-arabino-heptulosonate 7-phosphate (DAHP) synthase present in contemporary strains ofEscherichia coli have been proposed recently [Ahmad et al. (1986) J Bacteriol 165:146–154]. The phylogenetic subdivision of gram-negative prokaryotes studied (Superfamily B) includes enteric… CONTINUE READING
