malfunction
the deletion mutant strain DELTAYGR169c shows no detectable growth phenotype. The only difference in pseudouridine formation in stable cellular RNAs is the absence of pseudouridine at position 31 in cytoplasmic and mitochondrial tRNAs. Complementation of the DELTAYGR169c strain by a plasmid bearing the wild-type YGR169c ORF restores pseudouridine31 formation in tRNA
