tRNA uridine55 | the purified Pus4p catalyzes the formation of pseudouridine55 in T7 in vitro transcripts of several yeast tRNA genes. In contrast to the known yeast pseudouridine synthase (Pus1) of broad specificity, no other uridines in tRNA molecules are modified by the cloned recombinant Pus4p | Saccharomyces cerevisiae | tRNA pseudouridine55 | - |

malfunction | the disruption of the YNL292w gene in yeast, which has no significant effect on the growth of yeast cells, leads to the complete disappearance of the pseudouridine55 formation activity in a cell-free extract | Saccharomyces cerevisiae |
