| methylene tetrahydrofolate dehydrogenase-methenyltetrahydrofolate cyclohydrolase | <chemical> Bifunctional enzyme which contains mg-nad dependent covalently linked methylenetetrahydrofolate dehydrogenase (EC 1.5.1.15) and methenyltetrahydrofolate cyclohydrolase (EC 3.5.4.9); usually found in prokaryotes Synonym: methf dehydrogenase-cyclohydrolase (26 Jun 1999) |

| GTP cyclohydrolase | <enzyme> (GTP cyclohydrolase I) or GTP 7,8-8,9-dihydrolase (pyrophosphate-forming) (GTP cyclohydrolase II). An enzyme group that hydrolyzes the imidazole ring of GTP, releasing carbon-8 as formate. Two c-n bonds are hydrolyzed and the pentase unit is isomerised. This is the first step in the synthesis of folic acid from GTP.6 (GTP cyclohydrolase I) and GTP cyclohydrolase II. Chemical name: GTP 7,8-8,9-dihydrolase Registry number: EC 3.5.4.16 (12 Dec 1998) |
| methenyltetrahydromethanopterin cyclohydrolase | <enzyme> From methanobacterium thermoautotrophicum; catalyses the energy-independent hydrolysis of 5,10-methenyl-5,6,7,8-tetrahydromethanopterin to 5-formyl-h4mpt Registry number: EC 3.5.4.27 Synonym: 5,10-methenyl-h4mpt cyclohydrolase, 5,10-mh4mpt cyclohydrolase, 5,10-methenyltetrahydromethanopterin cylohydrolase (26 Jun 1999) |
| N5,N10-methenyltetrahydrofolate | A one-carbon derivative of tetrahydrofolate; used in purine biosynthesis. N5,N10-methylenetetrahydrofolate reductase, an enzyme that converts N5,N10-m ethylenetetrahydrofolate to N5,N10-methyl enyltetrahydrofolate using NADP+; a deficiency of this enzyme results in an accumulation of l-homocysteine and severe neurological disturbances.

| 5,10-methenyltetrahydrofolate synthetase | <enzyme> Chemical name: 5-formyltetrahydrofolate cyclo-ligase (ADP-forming) Registry number: EC 6.3.3.2 Synonym: 5,10-mthf synthetase, 5-formyl tetrahydrofolate cyclodehydrase, 5-formyltetrahydrofolate cyclo-ligase (26 Jun 1999) |
Synonyms : 5, 10-MTHF Cyclohydrolase, 5, 10-Methenyltetrahydrofolate 5-Hydrolase (Decyclizing), 5, 10-Methenyltetrahydrofolate Cyclohydrolase, 5, 10 MTHF Cyclohydrolase, 5, 10 Methenyltetrahydrofolate Cyclohydrolase, Cyclohydrolase, 5, 10-MTHF
| methenyltetrahydrofolate cyclohydrolase |
[EC 3.5.4.9] an enzyme activity of the hydrolase class that catalyzes the cleavage of 5,10-methenyltetrahydrofolate to 10-formyltetrahydrofolate, a step in the system of folate-mediated one-carbon transfer reactions. The enzyme activity is part of a trifunctional enzyme that also includes methylenetetrahydrofolate dehydrogenase (NADP+) and formate–tetrahydrofolate ligase activities.
