Its E domain interacts with the sPG synthesis complex, FtsWIQLB, and its SPOR domain interacts with denuded glycan (dnG), intermediates of sPG degradation. Here we used single-molecule tracking of FtsN and FtsW to investigate how FtsN coordinates the two opposing processes. We found that the SPOR domain binds to dnG cooperatively. This binding sequesters FtsWIQLB on dnG, which we call the dnG-track, and prevents dnG degradation. SPOR domain’s release from dnGs exposes dnGs to degradation, moves FtsN to the sPG synthesis track and activates FtsWIQLB. In addition, FtsN self-interacts through the SPOR domain, promoting the multimerization of FtsWIQLB on both tracks. This self-interaction may create a sensitive switch, regulating FtsN’s partitioning between dnG- and sPG-tracks to coordinate sPG degradation and synthesis while also controlling the balance between sequestered and active populations of the sPG synthesis complex.

It binds with NM23-H2, a host nucleoside diphosphate (NDP) kinase, to stimulate GTP loading of the dynamin-related protein (DRP1) GTPase, which triggers mitochondrial fission, inhibits mitochondrial antiviral signalling protein (MAVS) aggregation and impairs interferon responses in cell lines. An NM23-H2-binding-defective vBcl-2 mutant fails to evoke fission, leading to defective virion assembly due to activated MAVS–IFN signalling. Notably, we identify two key interferon-stimulated genes restricting vBcl-2-dependent virion morphogenesis. Using a high-throughput drug screening, we discover an inhibitor targeting vBcl-2–NM23-H2 interaction that blocks virion production in vitro.
