The pteridines in their multitude of forms fulfill many roles in nature ranging from pigments to cofactors for numerous redox and one-carbon transfer reactions. This extraordinary diversity of function is unified by the unique chemistry of the pterid

Tritium-labeled [6 S ]-tetrahydropteroylpolyglutamates of high radiospecific activity were prepared from the corresponding pteroylpolyglutamates. Malic enzyme and d,l -[2- 3 H]malate were used as a generating system to produce [4A- 3 H]NADPH which wa

Dihydrofolate and dihydropteroylpolyglutamates inhibit pig liver methylenetetrahydrofolate reductase. In all cases the inhibition is linearly competitive with respect to methylenetetrahydrofolate. The Ki values decrease with each additional glutamyl

The technique of human jejunal perfusion was used to study the process of digestion and absorption of conjugated folates in five healthy volunteers. The test solution of isotonic saline contained equimolar concentrations of purified [3H]pteroylmonogl

In contrast to (+)5,10-methylenetetrahydropteroylmonoglutamate which does not bind to Lactobacillus casei thymidylate synthetase, the corresponding tetraglutamate analog binds to a single site with a KD = 2 × 10−5 M. Alkylation of one of the enzym

Tissue folate polyglutamate chain lengths have been estimated by incorporation of the 5,10-methylenetetrahydrofolate polyglutamate form of the cofactor into ternary complexes with Lactobacillus casei thymidylate synthetase and [3H]fluorodeoxyuridylat

(l)-Tetrahydropteroyltriglutamate and (l)-tetrahydropteroylhexaglutamate were prepared and tested as substrates for thymidylate synthetase (EC 2.1.1.6) (methylenetetrahydrofolate:deoxyuridylate C-methyltransferase) from Lactobacillus casei. Both tetr
