Enzymes for Research, Diagnostic and Industrial Use

preQ1 synthase

Cat No.
EXWM-1606
Description
The reaction occurs in the reverse direction. This enzyme catalyses one of the early steps in the synthesis of queuosine (Q-tRNA), and is followed by the action of EC 2.4.2.29, queuine tRNA-ribosyltransferase. Queuosine is found in the wobble position of tRNAGUN in Eukarya and Bacteria and is thought to be involved in translational modulation. The enzyme is not a GTP cyclohydrolase, as was thought previously based on sequence-homology studies.
Form
Liquid or lyophilized powder
Enzyme Commission Number
CAS No.
1256460-80-6
Storage
Store it at +4 ºC for short term. For long term storage, store it at -20 ºC~-80 ºC.
Synonyms
YkvM; QueF; preQ0 reductase; preQ0 oxidoreductase; 7-cyano-7-deazaguanine reductase; queuine synthase (incorrect as queuine is not the product); queuine:NADP+ oxidoreductase (incorrect as queuine is not the product)
Reaction
7-aminomethyl-7-carbaguanine + 2 NADP+ = 7-cyano-7-carbaguanine + 2 NADPH + 2 H+
