Protein

S-adenosyl-L-methionine-dependent tRNA 4-demethylwyosine synthase

Gene

TYW1

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

Functioni

Component of the wybutosine biosynthesis pathway. Wybutosine is a hyper modified guanosine with a tricyclic base found at the 3'-position adjacent to the anticodon of eukaryotic phenylalanine tRNA. Catalyzes the condensation of N-methylguanine with 2 carbon atoms from pyruvate to form the tricyclic 4-demethylwyosine, an intermediate in wybutosine biosynthesis (By similarity).By similarity2 Publications

Miscellaneous

Present with 5410 molecules/cell in log phase SD medium.1 Publication

Catalytic activityi

N1-methylguanine(37) in tRNA(Phe) + pyruvate + S-adenosyl-L-methionine = 4-demethylwyosine(37) in tRNA(Phe) + L-methionine + 5'-deoxyadenosine + CO2 + H2O.

Cofactori

[4Fe-4S] cluster1 PublicationNote: Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine.1 Publication
