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-molybdopterin (Mo-MPT) cofactor 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.
