CC   -!- PATHWAY: Cofactor biosynthesis; 7,8-dihydroneopterin triphosphate
CC       biosynthesis; 7,8-dihydroneopterin triphosphate from GTP: step 1/1.
CC   -!- INDUCTION: Repressed by zinc, via zur. {ECO:0000269|PubMed:12426338}.
CC   -!- SIMILARITY: Belongs to the GTP cyclohydrolase IV family. {ECO:0000305}.
CC   -!- CAUTION: Was originally thought to be a zinc uptake system.
CC       {ECO:0000305|PubMed:12426338}.
