| Abstract: | Summary Four genes specifying the enzymes thymidine phosphorylase, purine nucleoside phosphorylase, deoxyribomutase and deoxyriboaldolase were mapped by transduction with phage P1. All pairs show greater than 90 per cent co-transduction. The gene order was found to be dra-tpp-drm-pup, and the gene cluster was shown to lie between the hsp and ser B loci on the chromosome map of Escherichia coli.This work is supported by Grant No. B/SR/3113 from the Science Research Council. |
