Fine Structure of Bacillus subtilis
The fine structure of Bacillus subtilis has been studied by observing sections fixed in KMnO(4), OsO(4), or a combination of both. The majority of examinations were made in samples fixed in 2.0 per cent KMnO(4) in tap water. Samples were embedded in butyl methacrylate for sectioning. In general, KMnO(4) fixation appeared to provide much better definition of the boundaries of various structures ...
متن کاملFine Structure Observed in 50s Ribosomal Subunits of Bacillus Subtilis
Short papers submitted expressly for this section, reporting original and significant findings of immediate interest and judged to be acceptable without major revision, will be published within approximately three months. See inside back cover for details. In the course of a study on the arrangement of the ribonucleoprotein in the bacterial cell (12), structural features were observed in purifi...
متن کاملSpoVT: From Fine-Tuning Regulator in Bacillus subtilis to Essential Sporulation Protein in Bacillus cereus
Sporulation is a highly sophisticated developmental process adopted by most Bacilli as a survival strategy to withstand extreme conditions that normally do not support microbial growth. A complicated regulatory cascade, divided into various stages and taking place in two different compartments of the cell, involves a number of primary and secondary regulator proteins that drive gene expression ...
متن کاملBacillus subtilis
A cloned chemotaxis operon has been characterized. Thirteen representative che mutations from different complementation groups were localized on the physical map by recombination experiments. The use of integration plasmids established that at least 10 of these complementation groups within this locus are cotranscribed. An additional three complementation groups may form part of the same transc...
متن کاملCrystal structure of Bacillus subtilis signal peptide peptidase A.
Signal peptide peptidase A (SppA) is a membrane-bound self-compartmentalized serine protease that functions to cleave the remnant signal peptides left behind after protein secretion and cleavage by signal peptidases. SppA is found in plants, archaea and bacteria. Here, we report the first crystal structure of a Gram-positive bacterial SppA. The 2.4-Å-resolution structure of Bacillus subtilis Sp...
