title: Histochemical localization of thiamine pyrophosphatase in the lomasomes in asci of Arthroderma vanbreuseghemii.
abstract: Thiamine pyrophosphatase localization in asci of Arthroderma vanbreuseghemii was investigated histochemically by electron microscopy. The reaction product of this enzyme was demonstrated in some paramural membranous structures that are believed to represent lomasomes. This observation suggests that at least a certain number of lomasomes might be involved in cell wall synthesis and thus behave in a manner similar to the Golgi apparatus in higher eukaryotic cells.
