Organism

Drosophila melanogaster (Fruit fly) [Complete proteome]

Taxonomic identifier

7227 [NCBI]

Taxonomic lineage

Eukaryota › Metazoa › Arthropoda › Hexapoda › Insecta › Pterygota › Neoptera › Endopterygota › Diptera › Brachycera › Muscomorpha › Ephydroidea › Drosophilidae › Drosophila › Sophophora

Protein attributes

Sequence length	309 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	May play a role in spermatogenesis.
Catalytic activity	5,10-methylenetetrahydrofolate + NAD+ = 5,10-methenyltetrahydrofolate + NADH. 5,10-methenyltetrahydrofolate + H2O = 10-formyltetrahydrofolate.
Cofactor	Magnesium.
Subunit structure	Homodimer.
Subcellular location	Mitochondrion.
Developmental stage	Expressed in developing tissues and at high levels in adult tissues. Isoform A shows male-specific expression. Ref.1
Miscellaneous	This NAD-dependent bifunctional enzyme has very different kinetic properties than the larger NADP-dependent trifunctional enzyme and is unique in that it requires formation of an enzyme-magnesium complex to allow binding of NAD.
Sequence similarities	Belongs to the tetrahydrofolate dehydrogenase/cyclohydrolase family.
