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

Folates in vivo undergo oxidative cleavage, giving pterin and p-aminobenzoylglutamate (pABAGlu) moieties. These breakdown products are excreted in animals, but their fate is unclear in microorganisms and unknown in plants. As indirect evidence from this and previous studies strongly suggests

The major route of folate turnover is by catabolic cleavage of the C9-N10 bond producing p-aminobenzoylglutamate (pABG) and its primary excretory form, p-acetamidobenzoylglutamate (ApABG). We hypothesize that total pABG (ApABG + pABG) excretion parallels both the mass of body folate

New stable isotope dilution assays were developed for the simultaneous quantitation of the folates 5-methyltetrahydrofolic acid, 5-formyltetrahydrofolic acid, tetrahydrofolic acid, 10-formylfolic acid, and folic acid as well as for their catabolites para-aminobenzoylglutamate (pABG) and acetyl-para-aminobenzoylglutamate (ApABG) in clinical samples.

Folate is shown to react with singlet-excited state of riboflavin in a diffusion controlled reaction and with triplet-excited state of riboflavin in a somewhat slower reaction with (3)k(q) = 4.8 × 10(8) L mol(-1) s(-1) in aqueous phosphate buffer at
