6.1.1.3	ATP + L-threonine + tRNAThr	Escherichia coli threonine tRNA is not aminoacylated by the Haloferax volcanii enzyme. The Escherichia coli mutant tRNAThr having U73 is threonylated by the Haloferax volcanii enzyme. The discriminator base U73 of Haloferax volcanii tRNAThr is a strong determinant for the recognition by threonyl-tRNA synthetase	Haloferax volcanii	AMP + diphosphate + L-threonyl-tRNAThr	-	?
