Dans cette publication, les auteurs ont montré que la protéine CotE guide l'assemblage des protéines CotY et ExsY par un processus bidirectionnel et asymétrique. Les images montrant toutes les étapes de la localisation dynamique de la protéine ont été obtenues par microscopie à illumination de structure à super-résolution (SR-SIM). L'une de ces images a été choisie pour la couverture de mSphere (n° 6).

Légende de l'image: Spores of Bacillus cereus are surrounded by an outermost layer, the exosporium, formed by glycosylated proteins whose assembly is guided by so-called morphogenetic proteins. The featured image shows colored variations of B. cereus sporulating cells observed by super-resolution structure illumination microscopy (SR-SIM). In the central panel, yellow signals represent the fluorescence of the morphogenetic protein CotE fused to a SNAP tag and show all steps of the dynamic localization of the protein at one pole, two poles, and around the forespore.

The article by Lablaine et al. in this issue shows that the morphogenetic protein CotE guides CotY and ExsY assembly in a bidirectional and asymmetric process.
