MetaCyc Pathway: tetrahydropteridine recycling in Enterobacter asburiae PDN3

Add experiment(s):


4a-hydroxytetrahydrobiopterin dehydratase:
a 4a-hydroxytetrahydrobiopterin→6,7-dihydrobiopterin + H2O
(spontaneous) (EC 4.2.1.96)
No genes
6,7-dihydropteridine reductase (in reverse):
6,7-dihydrobiopterin + NAD(P)H + H+→5,6,7,8-tetrahydrobiopterin + NAD(P)+
(EC 1.5.1.34)

Candidate genes for each reaction are identified from best hits to MetaCyc; by matching EC numbers (which are assigned by TIGRFam, SEED, or best hits to KEGG); or by matching SEED roles to KEGG reactions to MetaCyc reactions. See the "Protein" tab of each gene for more information
