Isolation and characterization of mutations in the Escherichia coli regulatory protein XapR.

Journal of bacteriology - 1 Jul 1999

Jørgensen C, Dandanell G

Abstract excerpt

In this work, the LysR-type protein XapR has been subjected to a mutational analysis. XapR regulates the expression of xanthosine phosphorylase (XapA), a purine nucleoside phosphorylase in Escherichia coli. In the wild type, full expression of XapA requires both a functional XapR protein and the inducer xanthosine. Here we show that deoxyinosine can also function as an inducer in the wild type, although not to...
