Protein Family Models

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. [1]. 11796730. Crystal structure of the productive ternary complex of. dihydropyrimidine dehydrogenase with NADPH and 5-iodouracil..

This family includes both class I and class II oxidoreductases and also NADH oxidases and peroxidases. This domain is actually a small NADH binding domain within a larger FAD binding domain.

This family consists of various amine oxidases, including maze polyamine oxidase (PAO) [1] and various flavin containing monoamine oxidases (MAO). The aligned region includes the flavin binding site of these enzymes. The family also contains phytoene dehydrogenases and related enzymes. In vertebrates MAO plays an important role regulating the intracellular levels of amines via there oxidation; these include various neurotransmitters, neurotoxins and trace amines [2]. In lower eukaryotes such as aspergillus and in bacteria the main role of amine oxidases is to provide a source of ammonium [3]. PAOs in plants, bacteria and protozoa oxidase spermidine and spermine to an aminobutyral, diaminopropane and hydrogen peroxide and are involved in the catabolism of polyamines [1]. Other members of this family include tryptophan 2-monooxygenase, putrescine oxidase, corticosteroid binding proteins and antibacterial glycoproteins. [1]. 9598979.

This family includes members that bind FAD. This family includes the flavoprotein subunits from succinate and fumarate dehydrogenase, aspartate oxidase and the alpha subunit of adenylylsulphate reductase. [1]. 8061609.
