Playing FtsZ before sporulation
Sorting it out, without clathrin lathrin-independent endocytosis is revealing itself at last. Intermediary organelles in this pathway have been difficult to identify, due in part to a dearth of markers and, until recently, difficulties in blocking the clathrin-dependent process. But now, has identified a set of endosomes that are uniquely C involved in clathrin-independent trafficking. Nichols'...
متن کاملBacterial Sporulation: FtsZ Rings Do the Twist
Formation of the polar Z ring is a crucial step in the establishment of cellular asymmetry during sporulation of Bacillus subtilis. New results suggest that the transition from medial to polar Z rings involves a dynamic FtsZ spiral structure that may transfer FtsZ from medial to polar sites.
متن کاملTwo dynamin-like proteins stabilize FtsZ rings during Streptomyces sporulation.
During sporulation, the filamentous bacteria Streptomyces undergo a massive cell division event in which the synthesis of ladders of sporulation septa convert multigenomic hyphae into chains of unigenomic spores. This process requires cytokinetic Z-rings formed by the bacterial tubulin homolog FtsZ, and the stabilization of the newly formed Z-rings is crucial for completion of septum synthesis....
متن کاملDynamics of FtsZ assembly during sporulation in Streptomyces coelicolor A3(2).
FtsZ, the bacterial tubulin homologue, is the main player in at least two distinct processes of cell division during the development of Streptomyces coelicolor A3(2). It forms cytokinetic rings and is required for the formation of both the widely spaced hyphal cross walls in the substrate mycelium and the specialized septation that converts sporogenic aerial hyphae into spores. The latter devel...
متن کامل"Endotrophic" sporulation.
The ability of vegetative cells to sporulate in water was first reported by Buchner ( 1890) and confirmed by Schreiber (1896) and Knaysi (1945). More recently, the replacement of a complex sporulation broth by water has proved to be a useful procedure for a variety of purposes (Grelet, 1951, 1955; Hardwick and Foster, 1952; Powell and Hunter, 1953; Foster and Perry, 1954; Perry and Foster, 1954...
