Protein
tRNA (guanine(37)-N1)-methyltransferase
Gene
TRM5, YHR070W
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Specifically methylates the N1 position of guanosine-37 in various cytoplasmic and mitochondrial tRNAs. Methylation is not dependent on the nature of the nucleoside 5' of the target nucleoside. This is the first step in the biosynthesis of wybutosine (yW), a modified base adjacent to the anticodon of tRNAs and required for accurate decoding. Postspliced cytoplasmic tRNAs are imported into the nucleus, where this first step seems to take place, after which they are reexported to the cytoplasm, where the yW sythesis is completed by cytoplasmic enzymes.4 Publications

Miscellaneousi

Miscellaneous

Present with 4120 molecules/cell in log phase SD medium.
It is unsure how the mitochondrial and cytoplasmic forms of this protein are produced. The cytoplasmic form may be produced by alternative initiation at a downstream in-frame AUG codon at position 34, lacking a mitochondrial transit peptide.
