Guanosine + Phosphate → Guanine + Ribose 1-phosphate
Phosphate + Xanthosine → Ribose 1-phosphate + Xanthine
Adenosine + Phosphate → Adenine + Ribose 1-phosphate
Adenosine + Hydrogen Ion + Water → Ammonium + Inosine
Phosphoribosyl pyrophosphate + Xanthine → Xanthylic acid + diphosphate
xanthine-guanine phosphoribosyltransferase
Ribose 1-phosphate → D-Ribose 5-phosphate
Inosine + Phosphate → Hypoxanthine + Ribose 1-phosphate
