Tetrahydrofolate biosynthesis and distribution in higher plants

Biochemical Society Transactions, 2005
One-carbon transfer reactions are mediated by H4F (tetrahydrofolate), a soluble coenzyme (vitamin B9) that is synthesized de novo by plants and microorganisms, and absorbed from the diet by animals. H4F synthesis in plants is quartered between the plastids, the cytosol and the mitochondria, a spatial distribution that is not observed in the other ...

Purification of tetrahydrofolate dehydrogenase by affinity chromatography

Biochimica et Biophysica Acta (BBA) - Enzymology, 1972
Abstract Tetrahydrofolate dehydrogenase (5,6,7,8-tetrahydrofolate:NADP + oxidoreductase, EC 1.5.1.3; formerly known as dihydrofolate reductase) from a subline of the L1210 lymphoma has been purified to apparent homogeneity with high recovery by simple steps using agarose to which the enzyme inhibitor amethopterin was coupled. A crude (NH 4 ) 2 SO 4

Tetrahydrofolate cofactors in the housefly Musca domestica

Comparative Biochemistry and Physiology, 1969
Abstract 1. 1. Dialyzed aqueous extract of acetone powder of houseflies was chromatographed on a DEAE column. 2. 2. Three tetrahydrofolate cofactors were distinctly separated and measured by microbial assays. 3. 3. Chicken pancreas conjugase was used to detect any polyglutamate derivatives. 4. 4.

Cytochemical Identification of Tetrahydrofolate in Human Leukocytes

American Journal of Clinical Pathology, 1979
Utilizing the ability of molybdenum dioxide dichloride to form a black insoluble precipitate with tetrahydrofolate, a cytochemical test for rapid detection of tetrahydrofolate in human leukocytes was developed. The test may be useful in distinguishing deficiency of vitamin B12 or folate or both from other disorders of erythropoiesis characterized by ...
