CC   -!- FUNCTION: Involved in tetrahydrobiopterin biosynthesis (By
CC       similarity).
CC   -!- CATALYTIC ACTIVITY: (6R)-6-(L-erythro-1,2-dihydroxypropyl)-
CC       5,6,7,8-tetrahydro-4a-hydroxypterin = (6R)-6-(L-erythro-1,2-
CC       dihydroxypropyl)-7,8-dihydro-6H-pterin + H(2)O.
CC   -!- SIMILARITY: Belongs to the pterin-4-alpha-carbinolamine
CC       dehydratase family.
