Guanylate kinases (GMKs) are involved in the salvage pathway of mono-phosphorylated guanosine (GMP) nucleosides to GDP therefore being essential in nucleotide maturation (Stolworthy & Black 2001). By introducing transgenic thymidine kinases (TKs) into tumor cells, a bottleneck occurs by overexpression of mono-phosphorylated intermediates. To overcome the accumulation of these non-toxic molecules, Willmon, Krabbenhoft, & Black (2006) fused the herpes simplex virus thymidine kinase (HSV-TK) to the guanylate kinase from M. musculus and demonstrated enhanced tumor killing in vitro.

The iGEM team Freiburg_Bioware provides the mGMK BioBrick part within the ‘Virus Construction Kit’ for therapeutical applications. Producing viral particles with encapsidated single-stranded DNA containing the fusion gene mGMK_TK enhances the efficacy of the prodrug-activating system leading to cell death of targeted tumor cells
