Protein

Formimidoyltransferase-cyclodeaminase

Gene

FTCD

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

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

Catalytic activityi

5-formimidoyltetrahydrofolate + L-glutamate = tetrahydrofolate + N-formimidoyl-L-glutamate.
5-formyltetrahydrofolate + L-glutamate = tetrahydrofolate + N-formyl-L-glutamate.
5-formimidoyltetrahydrofolate = 5,10-methenyltetrahydrofolate + NH3.

Involvement in diseasei

Glutamate formiminotransferase deficiency1 Publication

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionAutosomal recessive disorder. Features of a severe phenotype, include elevated levels of formiminoglutamate (FIGLU) in the urine in response to histidine administration, megaloblastic anemia, and mental retardation. Features of a mild phenotype include high urinary excretion of FIGLU in the absence of histidine administration, mild developmental delay, and no hematological abnormalities.
