== Function ==
[https://www.uniprot.org/uniprot/GSDA_ARATH GSDA_ARATH] Catalyzes the hydrolytic deamination of guanosine, producing xanthosine and ammonia. Deaminates exclusively guanosine and 2'-deoxyguanosine but no other aminated purines, pyrimidines, or pterines. Deamination of guanosine by GSDA is the only source of xanthosine production in Arabidopsis.<ref>PMID:24130159</ref>
