*Immune system engulfs the sodium urate crystals

*PRS Mutation Destroys Feedback 
Inhibition
**PRS is normally feedback inhibited by [[purine]] 
nucleotides
*Ribose 5-phosphate + ATP -(PRS)-> 
5-phosphoribosyl-1-pyrophosphate + AMP **Phosphoribosylpyrophosphate 
syntehtase (PRS): catalyzes the synthesis of phophoribosylpyrophosphate 
(PRPP)
**phophoribosylpyrophosphate (PRPP): vital precursor for all 
nucleotide synthesis
