Characterization of mutations that allow p-aminobenzoyl-glutamate utilization by Escherichia coli.

Journal of bacteriology - 1 Dec 1998

Hussein M J, Green J M, Nichols B P

Abstract excerpt

An Escherichia coli strain deficient in p-aminobenzoate synthesis was mutagenized, and derivatives were selected for growth on folic acid. Supplementation was shown to be due to p-aminobenzoyl-glutamate present as a breakdown product in commercial folic acid preparations. Two classes of mutations characterized by the minimum concentration of p-aminobenzoyl-glutamate that could support growth were obtained. Both...
