It is shown that AP4A is upregulated upon deletion of yqeK encoding the Ap4A hydrolase in S. aureus COL, and the ΔyqeK mutant was impaired in growth and survival during oxidative stress and after infection of murine macrophages, indicating that Ap4A contributes to the host-pathogen interactions in S. aureus.

These findings establish YqeK as a central regulator of dinucleotide homeostasis and RNA metabolism and provide the structural framework for Ap4N recognition by HD-domain phosphohydrolases.

N-hydroxyapiosporamide (NHAP) is established as a first-in-class Gi-selective inhibitor, providing a cell-permeable chemical scaffold for the optimization of next-generation agents to control Gi-signaling in cell-based systems and, ultimately, to target Gαi1-driven pathologies.
