20980241-3	2011	We have identified a substitution mutation (G388D) that reduces the activity of the GMP synthase Gua1 in budding yeast and the total G-nucleotide pool, leading to precipitous reductions in the GDP/GTP ratio and ATP level in vivo.	Guanosine Diphosphate	193-196	GMP synthase (glutamine-hydrolyzing)	Saccharomyces cerevisiae S288C	97-101
