Enzyme Information
4.1.2.50 |
6-carboxytetrahydropterin synthase.
based on mapping to UniProt P65870
7,8-dihydroneopterin 3'-triphosphate + H(2)O = 6-carboxy-5,6,7,8- tetrahydropterin + acetaldehyde + triphosphate.
-!- 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-5,6,7,8- tetrahydropterin and sepiapterin to 6-carboxy-5,6,7,8- tetrahydropterin.
