Dihydroprymidine dehydrogenase catalyses the first and rate-limiting step of pyrimidine degradation by converting pyrimidines to the corresponding 5,6- dihydro compounds [1]. This doma ...	Domain II of the enzyme dihydroprymidine dehydrogenase binds FAD. Dihydroprymidine dehydrogenase catalyses the first and rate-limiting step of pyrimidine degradation by converting pyrimidines to the corresponding 5,6- dihydro compounds [1]. This domain carries two Fe4-S4 clusters.	Domain
A	PF22117	NADH-quinone oxidoreductase subunit 3, ferredoxin-like domain (Fer4_Nqo3)	NADH-quinone oxidoreductase subunit 3, ferredoxin-like domain	NADH-quinone oxidoreductase subunit 3 (Nqo3) is a component of respiratory complex I. This protein is located at the peripheral arm of the complex and consists of multiple domains. This entry represents the second ferredoxin-like domain which contain ...	NADH-quinone oxidoreductase subunit 3 (Nqo3) is a component of respiratory complex I. This protein is located at the peripheral arm of the complex and consists of multiple domains. This entry represents the second ferredoxin-like domain which contains Fe4-S4 cluster, one of the redox centers of the complex [1-5].	Domain
