Function of T4D structural dihydrofolate reductase in bacteriophage infection.

Various properties of the bacteriophage structural dihydrofolate reductase (DFR) have been examined to determine its function during phage infection. It has been found that a binding site for reduced nicotinamide adenine dinucleotide phosphate (NADPH), most likely on the DFR present in the phage tail plate, is required for phage viability. Attachment of adenosine diphosphoribose, an analogue of...

Calorimetric studies of ligand binding in R67 dihydrofolate reductase.

R67 dihydrofolate reductase (DHFR) is a novel bacterial protein that possesses 222 symmetry and a single active site pore. Although the 222 symmetry implies that four symmetry-related binding sites must exist for each substrate as well as for each cofactor, various studies indicate only two molecules bind. Three possible combinations include two dihydrofolate molecules, two NADPH molecules, or ...

QSAR Studies of Some Novel Triazines Inhibiting Dihydrofolate Reductase

In this paper the Multi-linear regression analysis has been applied for QSAR study. The relationship has been worked out between the Log 1/C values of a series of compounds and certain quantum chemical and energy descriptors. The QSAR studies of Triazines inhibiting dihydrofolate reductase based on quantum chemical and energy descriptors shows that among all the 28 QSAR models PA51 to PA 78, th...

Lactobacillus casei dihydrofolate reductase

1 The binding of a series of amide derivatives of methotrexate to Lactobacillus casei dihydrofolate reductase has been studied by inhibition constant measurements and by 'H n.m.r. spectroscopy. 2 Amide modification of the a-carboxylate of methotrexate was found to prevent interaction of the y-carboxylate with the imidazole of His 28. 3 Estimates of the contributions to the binding energy from t...

Genetic mutations in 57 and 58 codons gene of Plasmodium vivax dihydrofolate reductase

Introduction: The use of Sulfadoxine and pyrimethamine (SP) for treatment of vivax malaria is not common in most of malarious areas because of sensivity of this parasite to chloroquine. But, Plasmodium vivax isolates are exposed to SP because of mixed infection with P.falciparum and this subject has lead to emergence of mutations in P.vdhfr gene. As Plasmodium vivax is the most prevalent specie...
