Metabolite damage and its repair or pre-emption.
Linster C.L., Van Schaftingen E., Hanson A.D.

It is increasingly evident that metabolites suffer various kinds of damage, that such damage happens in all organisms and that cells have dedicated systems for damage repair and containment. First, chemical biology is demonstrating that diverse metabolites are damaged by side reactions of 'promiscuous' enzymes or by spontaneous chemical reactions, that the products are useless or toxic and that the unchecked buildup of these products can be devastating. Second, genetic and genomic evidence from prokaryotes and eukaryotes is implicating a network of new, conserved enzymes that repair damaged metabolites or somehow pre-empt damage. Metabolite (that is, small-molecule) repair is analogous to macromolecule (DNA and protein) repair and seems from comparative genomic evidence to be equally widespread. Comparative genomics also implies that metabolite repair could be the function of many conserved protein families lacking known activities. How--and how well--cells deal with metabolite damage affects fields ranging from medical genetics to metabolic engineering. << Less

Cloning and characterization of the human 5,10-methenyltetrahydrofolate synthetase-encoding cDNA.
Dayan A., Bertrand R., Beauchemin M., Chahla D., Mamo A., Filion M., Skup D., Massie B., Jolivet J.
Methenyltetrahydrofolate synthetase (MTHFS) catalyses the obligatory initial metabolic step in the intracellular conversion of 5-formyltetrahydrofolate to other reduced folates. We have isolated and sequenced a human MTHFS cDNA which is 872-bp long and codes for a 203-amino-acid protein of 23,229 ... >> More
Methenyltetrahydrofolate synthetase (MTHFS) catalyses the obligatory initial metabolic step in the intracellular conversion of 5-formyltetrahydrofolate to other reduced folates. We have isolated and sequenced a human MTHFS cDNA which is 872-bp long and codes for a 203-amino-acid protein of 23,229 Da. Escherichia coli BL21(DE3), transfected with pET11c plasmids containing an open reading frame encoding MTHFS, showed a 100-fold increase in MTHFS activity in bacterial extracts after IPTG induction. Northern blot studies of human tissues determined that the MTHFS mRNA was expressed preferentially in the liver and Southern blot analysis of human genomic DNA suggested the presence of a single-copy gene. << Less

Primary structure and tetrahydropteroylglutamate binding site of rabbit liver cytosolic 5,10-methenyltetrahydrofolate synthetase.
Maras B., Stover P., Valiante S., Barra D., Schirch V.
The primary sequence of 5,10-methenyltetrahydrofolate synthetase from rabbit liver was determined by amino acid sequencing of the purified enzyme. The enzyme contains 201 amino acid residues with a predicted mass of 22,779 Da. The enzyme is located in the cytosolic fraction of liver homogenates. C ... >> More
The primary sequence of 5,10-methenyltetrahydrofolate synthetase from rabbit liver was determined by amino acid sequencing of the purified enzyme. The enzyme contains 201 amino acid residues with a predicted mass of 22,779 Da. The enzyme is located in the cytosolic fraction of liver homogenates. Carbodiimide-activated 5-formyltetrahydropteroylmonoglutamate and the pentaglutamate form of the substrate both irreversibly inactivate the enzyme by forming a covalent bond to Lys-18. Non-activated 5-formyltetrahydropteroylpentaglutamate protected against this inactivation. Substrate specificity studies showed that increasing the number of glutamate residues from zero to five on 5-formyltetrahydropteroate results in a 2 order of magnitude increase in the affinity of the substrate for the enzyme but only a 3-fold increase in the value of Vmax. << Less

The metabolic role of leucovorin.
Stover P., Schirch V.
Interest in determining if leucovorin, known chemically as 5-formyltetra-hydrofolate, plays a role in one-carbon metabolism is reemerging. While investigations in the 1940s suggested it was an important donor of one-carbon units in folate-mediated biosynthetic reactions, studies between the 1950s ... >> More
Interest in determining if leucovorin, known chemically as 5-formyltetra-hydrofolate, plays a role in one-carbon metabolism is reemerging. While investigations in the 1940s suggested it was an important donor of one-carbon units in folate-mediated biosynthetic reactions, studies between the 1950s and 1980s disproved this hypothesis and dismissed its presence in biological systems as artifactual. Recently, new data has focused attention on the possible biological function of this compound that is widely used in cancer chemotherapy. << Less
