UniProtKB - Q9ZCE8 (MIAB_RICPR)
Protein
tRNA-2-methylthio-N(6)-dimethylallyladenosine synthase
Gene
miaB
Organism
Rickettsia prowazekii (strain Madrid E)
Status
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
- [sulfur carrier]-SH + AH2 + N6-dimethylallyladenosine37 in tRNA + 2 S-adenosyl-L-methionine = 2-methylsulfanyl-N6-dimethylallyladenosine37 in tRNA + 5'-deoxyadenosine + [sulfur carrier]-H + A + 2 H+ + L-methionine + S-adenosyl-L-homocysteineUniRule annotationEC:2.8.4.3UniRule annotation
Cofactori
[4Fe-4S] clusterUniRule annotationNote: Binds 2 [4Fe-4S] clusters. One cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine.UniRule annotation
