xanthine-guanine phosphoribosyltransferase
Guanosine + Phosphate → Guanine + Ribose 1-phosphate
Adenosine (→), Hydrogen Ion (→) Transport: Yersinia pseudotuberculosis YPIII, Periplasmic Space to Yersinia pseudotuberculosis YPIII, Cytosol
Xanthosine (→), Hydrogen Ion (→) Transport: Yersinia pseudotuberculosis YPIII, Periplasmic Space to Yersinia pseudotuberculosis YPIII, Cytosol
Inosine + Phosphate → Hypoxanthine + Ribose 1-phosphate
Phosphoribosyl pyrophosphate + Xanthine → Xanthylic acid + diphosphate
Ribose 1-phosphate → D-Ribose 5-phosphate
Adenosine + Phosphate → Adenine + Ribose 1-phosphate
Adenosine + Hydrogen Ion + Water → Ammonium + Inosine
Phosphate + Xanthosine → Ribose 1-phosphate + Xanthine
