Enzyme Commission Summary:
Binds Zn2+. Isolated from the bacteria Bacillus subtilis and Escherichia coli. The reaction is part of the biosynthesis pathway of queuosine. The enzyme from Escherichia coli can also convert 6-pyruvoyl tetrahydropterin and sepiapterin to 6-carboxy-5,6,7,8-tetrahydropterin [McCarty09].
