Mapping of a new pan mutation in Escherichia coli K-12

Abstract

A previously unmapped pan gene was localized in an Escherichia coli K-12 strain using Hfr and F′ matings and by transduction studies. This Pan− mutation was shown by supplementation studies to impart a block in pantoate biosynthesis. The pan gene cotransduced with rha, metB, and argE placing it at 87 min.
