Fourteen recombinants induced no thymidine kinase, 12 induced type 1 thymidine kinase and 10 induced type 2 thymidine kinase. Correlation of these results with restriction endonuclease analysis of the DNA of the recombinants with five restriction endonucleases (XbaI, EcoRI, HpaI, HsuI, and BglII) allowed mapping of the type 1 thymidine kinase gene at 0.300 to 0.309 map unit and the type 2 thymidine kinase gene at 0.295 to 0.315 map unit., UL https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-49-2-235
