12590583-6	2003	Here we used 5-methyl-H(4)B to investigate how pterin structure influences radical formation and associated catalytic steps.	Pterins	47-53	H4 clustered histone 4	Homo sapiens	22-27	
12590583-10	2003	A crystal structure of 5-methyl-H(4)B-bound iNOSoxy revealed that there are minimal changes in conformation of the bound pterin or in its interactions with the protein as compared to H(4)B.	Pterins	121-127	H4 clustered histone 4	Homo sapiens	32-37
