Biosynthesis of 4-aminobenzoate in Escherichia coli.

abstract：:The major cotransduction gap of the Escherichia coli chromosome extends from mini 31 to 34. We have inserted transposons through this gap which, by sequential transduction, link sbcA (min 29.8) with manA (min 35.7) and thus eliminate the gap. These results indicate that the length of DNA in the region, as measured by ...
