Thymidylate synthase activity. It is involved in the biological process described with: dTMP biosynthetic process.

Folylpolyglutamate synthase; Catalyzes conversion of folates to polyglutamate derivatives allowing concentration of folate compounds in the cell and the intracellular retention of these cofactors, which are important substrates for most of the folate-dependent enzymes that are involved in one-carbon transfer reactions involved in purine, pyrimidine and amino acid synthesis; Belongs to the folylpolyglutamate synthase family.

Folate gamma-glutamyl hydrolase; Gamma-glutamyl-peptidase activity. It is involved in the biological process described with: tetrahydrofolylpolyglutamate metabolic process.

Serine hydroxymethyl transferase (Shmt) encodes a conserved pyridoxal phosphate-containing enzyme that converts serine into glycine and N5,N10-methylentetrahydrofolate. This reaction represents a major source for activated C1 units and tetrahydrofolate-mediated C1 metabolism; Belongs to the SHMT family.

Thioredoxin reductase 2, mitochondrial; Thioredoxin system is a major player in glutathione metabolism, due to the demonstrated absence of a glutathione reductase. Functionally interacts with the Sod/Cat reactive oxidation species (ROS) defense system and thereby has a role in preadult development and life span. Lack of a glutathione reductase suggests antioxidant defense in Drosophila, and probably in related insects, differs fundamentally from that in other organisms; Belongs to the class-I pyridine nucleotide-disulfide oxidoreductase family.

C-1-tetrahydrofolate synthase, cytoplasmic; Pugilist (pug) encodes the trifunctional enzyme methylenetetrahydrofolate dehydrogenase involved in the pigmentation of pteridines and ommochromes; In the C-terminal section; belongs to the formate-- tetrahydrofolate ligase family.

GTP cyclohydrolase 1; Isoform B is required for eye pigment production, Isoform C may be required for normal embryonic development and segment pattern formation.

Delta-1-pyrroline-5-carboxylate synthase; Glutamate-5-semialdehyde dehydrogenase activity; glutamate 5-kinase activity; delta1-pyrroline-5-carboxylate synthetase activity. It is involved in the biological process described with: oxidation-reduction process; proline biosynthetic process; In the C-terminal section; belongs to the gamma-glutamyl phosphate reductase family.

Hydrolase activity; isopentenyl-diphosphate delta-isomerase activity. It is involved in the biological process described with: isoprenoid biosynthetic process; isopentenyl diphosphate biosynthetic process.
