Chemical Taxonomy
Taxonomy DescriptionThis compound belongs to the class of organic compounds known as pterin carboxylates. These are heterocyclic aromatic compounds containing a pterin moiety, in which one ring is substituted by one or more carboxylic acid groups. Pterin is a heterocyclic compound composed of a pteridine ring system (made up of a pyrazine fused to a pyrimidine), with a keto group and an amino group at the 2- and 4- positions, respectively.

Protein Details
• 6-carboxy-5,6,7,8-tetrahydropterin synthase
General function:
Coenzyme transport and metabolism
Specific function:
Catalyzes the conversion of 7,8-dihydroneopterin triphosphate (H2NTP) to 6-carboxy-5,6,7,8-tetrahydropterin (CPH4) and acetaldehyde. Can also convert 6-pyruvoyltetrahydropterin (PPH4) and sepiapterin to CPH4; these 2 compounds are probably intermediates in the reaction from H2NTP
Gene Name:
queD
Locus Tag:
PA2666
Molecular weight:
13.8 kDa
Reactions
7,8-dihydroneopterin 3'-triphosphate + H(2)O = 6-carboxy-5,6,7,8-tetrahydropterin + acetaldehyde + triphosphate.
