Systematic name YML014W
Gene name TRM9
Aliases KTI1
Feature type ORF, Verified
Coordinates Chr XIII:243225..244064
Primary SGDID S000004476


Description of YML014W: tRNA methyltransferase; catalyzes modification of wobble bases in tRNA anticodons to 2, 5-methoxycarbonylmethyluridine and 5-methoxycarbonylmethyl-2-thiouridine; may act as part of a complex with Trm112p; deletion mutation increases translational infidelity, including amino acid misincorporation and -1 frameshifting, and also confers resistance to zymocin; null mutant displays activation of stress responses[1][2][3][4]
