21235647-6	2011	Here we show that NSH1 is also able to hydrolyze xanthosine with high efficiency, and thus represents the leading activity in purine and pyrimidine breakdown in a cell.	pyrimidine	137-147	uridine-ribohydrolase 1	Arabidopsis thaliana	18-22	
19293370-9	2009	Mutants expressing the Arabidopsis enzyme or the homolog from rice (Oryza sativa) exhibit resistance toward toxic fluorouridine, fluorouracil, and fluoroorotic acid, providing clear evidence for a pivotal function of URH1 as regulative in pyrimidine degradation.	pyrimidine	239-249	uridine-ribohydrolase 1	Arabidopsis thaliana	217-221
