3349105-0	1988	Inhibition of GTP cyclohydrolase I by pterins.	Pterins	38-45	GTP cyclohydrolase 1	Homo sapiens	14-34	
23100563-2	2013	We demonstrate that Escherichia coli K1 infection of human brain microvascular endothelial cells (HBMECs) induces the expression of guanosine triphosphate cyclohydrolase (GCH1), the rate-limiting enzyme in pterin synthesis, thereby elevating levels of biopterin.	Pterins	206-212	GTP cyclohydrolase 1	Homo sapiens	171-175	
3106526-0	1986	Interferon-gamma enhances biosynthesis of pterins in peripheral blood mononuclear cells by induction of GTP-cyclohydrolase I activity.	Pterins	42-49	GTP cyclohydrolase 1	Homo sapiens	104-124	
7545102-7	1995	NO synthesis was prevented by an inhibitor of GTPCH, 2,4-diamino-6-hydroxypyrimidine, and this inhibition was completely reversed by administration of sepiapterin, a substrate for BH4 synthesis via pterin salvage pathway.	Pterins	156-162	GTP cyclohydrolase 1	Homo sapiens	46-51
