Cytosolic formimidoyltransferase-cyclodeaminase (FTCD) catalyzes the reaction of N-formiminoglutamate and tetrahydrofolate to form glutamate and 5-formiminotetrahydrofolate. The gene encoding the human enzyme has beeen cloned and its sequence can encode a protein homologous the the biochemically characterized porcine protein (Solans et al. 2000; Murley et al. 1993). The function of FTCD in vivo was established by identification of missense mutations that reduce enzyme activity in patients with glutamate formiminotransferase deficiency (Hilton et al. 2003). Human FTCD is inferred to be an octamer by homology to the porcine enzyme (Murley et al. 1993).
