Goblet-shaped Sub-units from the Wall of a Marine Gliding Microbe

Summary: Goblet-shaped sub-units from the wall of a gliding marine bacterium have been isolated. They are apparently largely proteinaceous, having a buoyant density in CsCl solution of 1.31 g/ml at 25 °C. Their ultrastructure revealed by electron microscopy allows the hypothesis that they function in vivo as secretory organelles.
