The isolation of fumB mutants of Escherichia coli.

Escherichia coli strains lacking the terminus region of the chromosome (min 29-36) due to an IS10-promoted deletion did not grow well in rich medium; they also did not grow on fumarate minimal medium because fumAC (min 35.7) is deleted. Strains with secondary mutations that partially suppress the deletion phenotype displayed healthier growth on rich medium and grew on minimal fumarate medium. These suppressor mutants had an IS10 insertion just upstream of the fumB structural gene (min 93.4). A strain with a Tn10 insertion at this location was constructed and used to delete nonessential fumB; fumB deletion mutants grew well on both rich and minimal fumarate media.[1]
