Pentose Phosphate Pathway Phosphoribosyl Pyrophosphate (PRPP) Amidophosphoribosyl-transferase (commitment step) 5-phosphoribosylamine Complex Pathway IMP dehydrogenase Adenylosuccinate synthase Xanthosine Monophosphate (XMP) Inosine Monophosphate (IMP) Adenylo-succinate Adenylosuccinate lyase GMP synthase GMP reductase AMP deaminase Guanine Adenine Nucleotidase Inosine Purine Nucleosidase/Phosphorylase Guanase Hypo-xanthine Xanthine oxido-reductase Xanthine oxoreductase Uric Acid Xanthine
AMP deaminase: Missing EC 22.214.171.124, an adenosine monophosphate deaminase. Both JGI and Manatee call an adenosine deaminase with EC 3.5.4.- Guanase: Missing EC 126.96.36.199, a guanine deaminase. RAST calls a hypothetical protein with EC 188.8.131.52 AT THE EXACT SAME BASE PAIRS that JGI and Manatee called an adenosine deaminase. Xanthine oxidoreductase: Missing EC 184.108.40.206 or 220.127.116.11. Xanthine oxoreductase: Same EC numbers as Xanthine Oxidoreductase OVERARCHING QUESTIONS: Is it an adenosine monophosphate deaminase or a guanine deaminase? What is xanthine and why does our organism appear to have no ability to do anything with it (same with other halophiles)?
BLAST Result for adenosine / guanine deaminase: Most were cytidine deaminases… But the second highest result was a guanine deaminase! Conclusion: Possibly a guanine deaminase?
