Protein

Multisite-specific tRNA:(cytosine-C(5))-methyltransferase

Gene

NCL1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Methylates cytosine to m5C at several positions in different tRNAs and pre-tRNAs containing intron. Able to modify tRNAs at all four positions (34, 40, 48 and 49) at which m5C has been found in tRNAs. May be involved in ribosome biogenesis as its disruption leads to increased sensitivity to the antibiotic paromomycin.2 Publications

Miscellaneous

Present with 16100 molecules/cell in log phase SD medium.1 Publication
