Protein Summary
Formiminotetrahydrofolate cyclodeaminase (TM1560) from
Thermotoga maritima (FTCD_CD, EC 4.3.1.4; COG3404, pfam04961) is involved in folate metabolism (PubMed:
15651027).
TM1560 is similar to protein domain of bifunctional, Golgi-associated formiminotransferase cyclodeaminase (PDB id: 1tt9) - a mammalian protein that plays important roles in coupling histidine catabolism with folate metabolism and integrating the Golgi complex with the vimentin intermediate filament cytoskeleton (PubMed:15272307).
TM1560 has methenyltetrahydrofolate cyclohydrolase-like fold (SCOP sunid:101261) - closed 5 helical bundle with left-handed twist.
