Fig. 7From: Silicanin-1 is a conserved diatom membrane protein involved in silica biomineralizationCryo-electron microscopy analysis of rSin1lum clusters. a Clusters at different pH values 60 min after adjustment to the indicated pH. The black arrows point to small clusters that consist of only 10–20 protein monomers. b Clusters at pH 5.2 (left) and pH 5.0 (right). The arrowheads point to neck regions between two clusters that are indicative of fusion eventsBack to article page
