Chemical Taxonomy
Taxonomy DescriptionThis compound belongs to the class of organic compounds known as alkaloids and derivatives. These are naturally occurring chemical compounds that contain mostly basic nitrogen atoms. This group also includes some related compounds with neutral and even weakly acidic properties. Also some synthetic compounds of similar structure are attributed to alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and more rarely other elements such as chlorine, bromine, and phosphorus.

Protein Details
• Putative xanthine dehydrogenase yagS FAD-binding subunit
General function:
Involved in flavin adenine dinucleotide binding
Specific function:
Xanthine + NAD(+) + H(2)O = urate + NADH
Gene Name:
yagS
Locus Tag:
PA1932
Molecular weight:
35.6 kDa
Reactions
Xanthine + NAD(+) + H(2)O = urate + NADH.
Hypoxanthine + NAD(+) + H(2)O = xanthine + NADH.
Protein Details
• Xanthine dehydrogenase molybdenum-binding subunit
General function:
Involved in oxidoreductase activity
Specific function:
Presumed to be a dehydrogenase, but possibly an oxidase. Participates in limited purine salvage (requires aspartate) but does not support aerobic growth on purines as the sole carbon source (purine catabolism). Deletion results in increased adenine sensitivity, suggesting that this protein contributes to the conversion of adenine to guanine nucleotides during purine salvage
