Cleavage of guanosine or inosine to respective bases and sugar-1-phosphate molecules

Gene Name:

deoD

Uniprot ID:

P0ABP8

Molecular weight:

25950

Reactions

General function:

Involved in hydrolase activity, hydrolyzing N-glycosyl compounds

Specific function:

Hydrolyzes both purine and pyrimidine ribonucleosides with a broad-substrate specificity with decreasing activity in the order uridine, xanthosine, inosine, adenosine, cytidine, guanosine

Gene Name:

rihC

Uniprot ID:

P22564

Molecular weight:

32560

General function:

Involved in hydrolase activity

Specific function:

Catalyzes the hydrolytic deamination of guanine, producing xanthine and ammonia

Gene Name:

guaD

Uniprot ID:

P76641

Molecular weight:

Reactions

General function:

Involved in flavin adenine dinucleotide binding

Specific function:

Xanthine + NAD(+) + H(2)O = urate + NADH

Gene Name:

yagS

Uniprot ID:

P77324

Molecular weight:

33858

Reactions

General function:

Involved in oxidoreductase activity

Specific function:

Xanthine + NAD(+) + H(2)O = urate + NADH

Gene Name:

yagR

Uniprot ID:

P77489

Molecular weight:

78088

Reactions

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

Gene Name:

xdhB

Uniprot ID:

Q46800

Molecular weight:

Reactions

General function:

Involved in oxidoreductase activity

Specific function:

Iron-sulfur subunit of the xanthine dehydrogenase complex

Gene Name:

xdhC

Uniprot ID:

Q46801

Molecular weight:

16922

General function:

Involved in purine-nucleoside phosphorylase activity

Specific function:

The nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the nucleoside molecule, with the formation of the corresponding free bases and pentose-1-phosphate. This protein can degrade all purine nucleosides except adenosine and deoxyadenosine
