CC -!- FUNCTION: Involved in tetrahydrobiopterin biosynthesis. Seems to both
CC prevent the formation of 7-pterins and accelerate the formation of
CC quinonoid-BH2. May also have a positive regulatory role in the
CC expression of phhA (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(4aS,6R)-4a-hydroxy-L-erythro-5,6,7,8-tetrahydrobiopterin =
CC (6R)-L-erythro-6,7-dihydrobiopterin + H2O; Xref=Rhea:RHEA:11920,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15642, ChEBI:CHEBI:43120; EC=4.2.1.96;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00434};
CC -!- SIMILARITY: Belongs to the pterin-4-alpha-carbinolamine dehydratase
CC family. {ECO:0000255|HAMAP-Rule:MF_00434}.
