Protein

tRNA-2-methylthio-N(6)-dimethylallyladenosine synthase

Gene

miaB

Organism
Proteus mirabilis (strain HI4320)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Catalyzes the methylthiolation of N6-(dimethylallyl)adenosine (i6A), leading to the formation of 2-methylthio-N6-(dimethylallyl)adenosine (ms2i6A) at position 37 in tRNAs that read codons beginning with uridine.UniRule annotation

Catalytic activityi

N(6)-dimethylallyladenine(37) in tRNA + sulfur-(sulfur carrier) + 2 S-adenosyl-L-methionine = 2-methylthio-N(6)-dimethylallyladenine(37) in tRNA + S-adenosyl-L-homocysteine + (sulfur carrier) + L-methionine + 5'-deoxyadenosine.UniRule annotation

Cofactori

Binds 2 4Fe-4S clusters. One cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine.UniRule annotation
