tRNA-2-methylthio-N6-dimethylallyladenosine synthase
Cat No.
EXWM-3429
Description
This bacterial enzyme binds two [4Fe-4S] clusters as well as the transferred sulfur. The enzyme is a member of the superfamily of S-adenosyl-L-methionine-dependent radical (radical AdoMet) enzymes. The sulfur donor is believed to be one of the [4Fe-4S] clusters, which is sacrificed in the process, so that in vitro the reaction is a single turnover. The identity of the electron donor is not known.
Form
Liquid or lyophilized powder
Enzyme Commission Number
Storage
Store it at +4 ºC for short term. For long term storage, store it at -20 ºC～-80 ºC.
Synonyms
MiaB; 2-methylthio-N-6-isopentenyl adenosine synthase; tRNA-i6A37 methylthiotransferase
Reaction
N6-dimethylallyladenine37 in tRNA + sulfur-(sulfur carrier) + 2 S-adenosyl-L-methionine + reduced electron acceptor = 2-methylthio-N6-dimethylallyladenine37 in tRNA + S-adenosyl-L-homocysteine + (sulfur carrier) + L-methionine + 5'-deoxyadenosine + electron acceptor (overall reaction); (1a) N6-dimethylallyladenine37 in tRNA + sulfur-(sulfur carrier) + S-adenosyl-L-methionine + reduced electron acceptor = 2-thio-N6-dimethylallyladenine37 in tRNA + (sulfur carrier) + L-methionine + 5'-deoxyadenosine + electron acceptor; (1b) S-adenosyl-L-methionine + 2-thio-N6-dimethylallyladenine37 in tRNA = S-adenosyl-L-homocysteine + 2-methylthio-N6-dimethylallyladenine37 in tRNA
