Molecular mechanism of regulation of the purine salvage enzyme XPRT by the alarmones pppGpp, ppGpp, and pGpp

The alarmones pppGpp and ppGpp mediate starvation response and maintain purine homeostasis to protect bacteria. In the bacterial phyla Firmicutes and Bacteroidetes, xanthine phosphoribosyltransferase (XPRT) is a purine salvage enzyme that produces the nucleotide XMP from PRPP and xanthine. Combining...
