General function:

Involved in folic acid binding

Specific function:

Catalyzes the methylation of glycine by using S-adenosylmethionine (AdoMet) to form N-methylglycine (sarcosine) with the concomitant production of S-adenosylhomocysteine (AdoHcy). Possible crucial role in the regulation of tissue concentration of AdoMet and of metabolism of methionine.

Gene Name:

GNMT

Uniprot ID:

Q14749

Molecular weight:

32742.0

General function:

Involved in catalytic activity

Specific function:

Folate-dependent enzyme, that displays both transferase and deaminase activity. Serves to channel one-carbon units from formiminoglutamate to the folate pool. Binds and promotes bundling of vimentin filaments originating from the Golgi (By similarity).

Gene Name:

FTCD

Uniprot ID:

O95954

Molecular weight:

General function:

Involved in dihydrofolate reductase activity

Specific function:

Key enzyme in folate metabolism. Contributes to the de novo mitochondrial thymidylate biosynthesis pathway. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis. Binds its own mRNA and that of DHFRL1.

Gene Name:

DHFR

Reactions

General function:

Involved in ATP binding

Specific function:

Contributes to tetrahydrofolate metabolism. Helps regulate carbon flow through the folate-dependent one-carbon metabolic network that supplies carbon for the biosynthesis of purines, thymidine and amino acids.

General function:

Involved in folic acid binding

Specific function:

Binds to folate and reduced folic acid derivatives and mediates delivery of 5-methyltetrahydrofolate to the interior of cells

Gene Name:

FOLR1

Uniprot ID:

General function:

Involved in folic acid binding

Specific function:

Transporter for the intake of folate. Uptake of folate in human placental choriocarcinoma cells occurs by a novel mechanism called potocytosis which functionally couples three components, namely the folate receptor, the folate transporter, and a V-type H(+)-pump.
