8540751-5	1995	The acyclonucleotide analogues were also studied as substrates of guanylate kinase, an enzyme believed to play a critical role in the conversion of acyclic phosphate and phosphonate derivatives of guanine to their antivirally active diphosphate derivatives.	Organophosphonates	170-181	guanylate kinase 1	Homo sapiens	66-82	
1316735-6	1992	The lack of phosphorylation of 9-(5,5-difluoro-5-phosphonopentyl)guanine by guanylate kinase is explained by the decreased nucleophilic character of the oxygen atoms of the phosphonate group rather than by inadequate binding to the GMP-binding site.	Organophosphonates	173-184	guanylate kinase 1	Homo sapiens	76-92
