Uridine 107-115 Ncs6p Saccharomyces cerevisiae S288C 27-32 17592039-6 2007 Deletion of the TUC1 gene together with a deletion of the ELP3 gene, which results in the lack of the mcm(5) side chain, removes all modifications from the wobble uridine derivatives of the cytoplasmic tRNAs specific for Gln, Lys, and Glu, and is lethal to the cell. Uridine 163-170 Ncs6p Saccharomyces cerevisiae S288C 16-20
