Folates break down in vivo to give pterin and p-aminobenzoylglutamate (pABAGlu) fragments, the latter usually having a polyglutamyl tail. Pilot studies have shown that plants can hydrolyze pABAGlu and its polyglutamates to p-aminobenzoate, a folate biosynthesis precursor. The enzymatic basis

The development of accurate and precise folate assays has been difficult, mainly because of folate instability. Large interassay and interlaboratory differences have been reported. We therefore developed a serum folate assay that measures folate and putative degradation products as p-aminobenzoylglutamate

Escherichia coli AbgT was first identified as a structural protein enabling the growth of p-aminobenzoate auxotrophs on exogenous p-aminobenzoyl-glutamate (M. J. Hussein, J. M. Green, and B. P. Nichols, J. Bacteriol. 180:6260-6268, 1998). The abg region includes abgA, abgB, abgT

Folate catabolism represents the major route of folate turnover in humans and involves cleavage of the C9-N10 bond producing a pterin and para-aminobenzoylglutamate (pABG). Thus, the quantitation of pABG and its acetylated more predominant counterpart para-acetamidobenzolyglutamate (apABG) may be useful

To estimate the rate of folate catabolism in pregnant and nonpregnant women and to derive the recommended dietary allowance for folate. Prospective, observational study. Rotunda Hospital, Dublin. WOMEN: Twenty-four healthy gravid women were studied once during each trimester and postpartum.
