Corrected sequence of the mannitol (mtl) operon in Escherichia coli.

The previously published sequences of the operator-promoter region of the mannitol operon of Escherichia coli and of the mtlD gene have been found to contain a number of errors. The major conclusions reported previously were correct, but additionally it is now clear that a C-terminal portion of mannitol-1-phosphate dehydrogenase (the mtlD gene product) exhibits significant sequence identity with an amino-terminal region of human liver fructose-6-phosphate-2-kinase:fructose-2,6-bisphosphatase.
