Description

Xanthosine, also known as xanthine riboside, belongs to the class of organic compounds known as purine nucleosides. Purine nucleosides are compounds comprising a purine base attached to a ribosyl or deoxyribosyl moiety. Xanthosine is a nucleoside derived from xanthine and ribose. Xanthosine exists in all living species, ranging from bacteria to plants to humans. In plants xanthosine is the biosynthetic precursor to 7-methylxanthosine which is produced by the action of the enzyme known as 7-methylxanthosine synthase. 7-Methylxanthosine in turn is the precursor to theobromine (the active alkaloid in chocolate), which in turn is the precursor to caffeine, the active alkaloid in coffee and tea. Within humans, xanthosine participates in a number of enzymatic reactions. In particular, xanthosine can be biosynthesized from xanthylic acid; which is catalyzed by the enzyme cytosolic purine 5'-nucleotidase. In addition, xanthosine can be converted into xanthine and ribose 1-phosphate; which is mediated by the enzyme purine nucleoside phosphorylase. Xanthosine monophosphate (XMP) is an intermediate in purine metabolism, formed from IMP (inosine monophosphate).

General function:: Involved in hydrolase activity
Specific function:: Hydrolyzes extracellular nucleotides into membrane permeable nucleosides.
Gene Name:: NT5E
Uniprot ID:: P21589
Molecular weight:: 57948.125

Reactions

Xanthylic acid + Water → Xanthosine + Phosphate	details

Enzyme Details

2. Cytosolic 5'-nucleotidase 1B

General function:: Involved in nucleotide binding
Specific function:: Dephosphorylates the 5' and 2'(3')-phosphates of deoxyribonucleotides. Helps to regulate adenosine levels (By similarity).
Gene Name:: NT5C1B
Uniprot ID:: Q96P26
Molecular weight:: 68803.055

Reactions

Xanthylic acid + Water → Xanthosine + Phosphate	details

Enzyme Details

3. Cytosolic 5'-nucleotidase 1A

General function:: Involved in nucleotide binding
Specific function:: Dephosphorylates the 5' and 2'(3')-phosphates of deoxyribonucleotides and has a broad substrate specificity. Helps to regulate adenosine levels in heart during ischemia and hypoxia.
Gene Name:: NT5C1A
Uniprot ID:: Q9BXI3
Molecular weight:: 41020.145

Reactions

Xanthylic acid + Water → Xanthosine + Phosphate	details

Enzyme Details

4. 5'(3')-deoxyribonucleotidase, cytosolic type

General function:: Involved in metal ion binding
Specific function:: Dephosphorylates the 5' and 2'(3')-phosphates of deoxyribonucleotides, with a preference for dUMP and dTMP, intermediate activity towards dGMP, and low activity towards dCMP and dAMP.
Gene Name:: NT5C
Uniprot ID:: Q8TCD5
Molecular weight:: Not Available

Reactions

Xanthylic acid + Water → Xanthosine + Phosphate	details

Enzyme Details

5. 5'(3')-deoxyribonucleotidase, mitochondrial

General function:: Involved in phosphatase activity
Specific function:: Dephosphorylates specifically the 5' and 2'(3')-phosphates of uracil and thymine deoxyribonucleotides, and so protects mitochondrial DNA replication from excess dTTP. Has only marginal activity towards dIMP and dGMP.
Gene Name:: NT5M
Uniprot ID:: Q9NPB1
Molecular weight:: Not Available

Reactions

Xanthylic acid + Water → Xanthosine + Phosphate	details

Enzyme Details

6. Inosine triphosphate pyrophosphatase

General function:: Involved in hydrolase activity
Specific function:: Pyrophosphatase that hydrolyzes the non-canonical purine nucleotides inosine triphosphate (ITP), deoxyinosine triphosphate (dITP) as well as 2'-deoxy-N-6-hydroxylaminopurine triposphate (dHAPTP) and xanthosine 5'-triphosphate (XTP) to their respective monophosphate derivatives. The enzyme does not distinguish between the deoxy- and ribose forms. Probably excludes non-canonical purines from RNA and DNA precursor pools, thus preventing their incorporation into RNA and DNA and avoiding chromosomal lesions.
Gene Name:: ITPA
Uniprot ID:: Q9BY32
Molecular weight:: 16833.23

Enzyme Details

7. Cytosolic 5'-nucleotidase 3

General function:: Involved in magnesium ion binding

Gene Name:: NT5C2
Uniprot ID:: P49902
Molecular weight:: 64969.2

Reactions

Xanthylic acid + Water → Xanthosine + Phosphate	details

Enzyme Details

9. Purine nucleoside phosphorylase

Gene Name:: PNP
Uniprot ID:: P00491
Molecular weight:: 32117.69

Reactions

Xanthosine + Phosphate → Xanthine + Ribose 1-phosphate	details
