Nucleotide Dependence and Cytoplasmic Localization
Many different proteins associate with microtubules, influencing their spatial organization and function. These include proteins of a structural nature, which link microtubules to one another or to other cellular organelles and which may stimulate tubulin assembly. The second group, the so-called dynamic microtubuleassociated proteins, move subcellular components along microtubules through nucl...
متن کاملMarine amoebae with cytoplasmic and perinuclear symbionts deeply branching in the Gammaproteobacteria
Amoebae play an important ecological role as predators in microbial communities. They also serve as niche for bacterial replication, harbor endosymbiotic bacteria and have contributed to the evolution of major human pathogens. Despite their high diversity, marine amoebae and their association with bacteria are poorly understood. Here we describe the isolation and characterization of two novel m...
متن کاملCytoplasmic DNA-containing bodies and the response of amoebae to dimidium bromide.
The growth of Amoeba proteus (T1P) and Amoeba discoides (T1D) in the trypanocidal phenanthridinium, dimidium bromide was examined. At concentrations of drug between 2 and 4 /ig/ ml, A. proteus divided twice before inhibition and death. A. discoides was able to undergo an additional cycle of division before death. At other concentrations there were no differences in their response. Heterotransfe...
متن کاملThe Golgi Apparatus in Amoebae
The appearance of enzymic activity during the development of the Golgi apparatus was studied by cytochemical staining of renucleated amoebae. In cells enucleated for 4 days, there was a great decline in size and number of Golgi bodies, or dictyosomes. Subsequent renucleation by nuclear transplantation resulted in a regeneration of Golgi bodies. Samples of amoebae were fixed and incubated for cy...
متن کاملNuclear Transplantation in Amoebae . II
1. A description is given of a method for replacing the original nucleus of an amoeba by a nucleus from another amoeba. This method has been used to study transfers of nuclei within a species (homotransfers) and between species (heterotransfers). The species used were A. proteus and A. discoides. 2. Removal of the nucleus from an amoeba inactivates the animal, so that movement is sporadic and u...
