Protein attributes
| Sequence length | 1353 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Key enzyme involved in purine catabolism. Catalyzes the oxidation of hypoxanthine to xanthine and the oxidation of xanthine to urate. Regulates the level of ureides and plays a role during plant growth and development and senescence. Ref.4 |
| Catalytic activity | Xanthine + NAD+ + H2O = urate + NADH. Hypoxanthine + NAD+ + H2O = xanthine + NADH. |
| Cofactor | Binds 2 2Fe-2S clusters By similarity. FAD By similarity. Binds 1 molybdenum ion (molybdopterin) per subunit By similarity. |
| Subunit structure | Homodimer By similarity. |
| Tissue specificity | Expressed in roots, leaves, stems, flowers and siliques. |
| Miscellaneous | Plants silencing simultaneously XDH1 and XDH2 show reduced growth, impaired silique development, increased seed sterility, precocious senescence of mature leaves and overaccumulation of xanthine (Ref.4). |
| Sequence similarities | Belongs to the xanthine dehydrogenase family. Contains 1 2Fe-2S ferredoxin-type domain. Contains 1 FAD-binding PCMH-type domain. |
| Sequence caution | The sequence CAB45451.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAB80207.1 differs from that shown. Reason: Erroneous gene model prediction. |
