Interactions between exogenous deoxyribonucleic acid and membrane vesicles isolated from competent and noncompetent Bacillus subtilis.
Competent cultures of Bacillus subtilis 168 have been fractionated into a high-competent and a low-competent fraction by a large-scale separation technique. Membrane vesicles isolated from both cell fractions are equally active in the transport of L-glutamate. Both membrane vesicle preparations seem to have similar endo- and exonuclease activities. Also, both preparations are capable of binding...
متن کاملRegulation of the transport system for C4-dicarboxylic acids in Bacillus subtilis.
Transport systems for C4-dicarboxylates, such as malate, fumarate and succinate, are poorly understood in Gram-positive bacteria. The whole genome sequence of Bacillus subtilis revealed two genes, ydbE and ydbH, whose deduced products are highly homologous to binding proteins and transporters for C4-dicarboxylates in Gram-negative bacteria. Between ydbE and ydbH, genes ydbF and ydbG encoding a ...
متن کاملMembrane Synthesis in Bacillus Subtilis
The results of several lines of investigation indicate that membrane growth in Bacillus subtilis does not occur at one or a small number of discrete zones. No indications of large regions of membrane conservation were observed. Kinetic labeling experiments of mesosomal and plasma membrane lipids indicate that the mesosomal lipids are not precursors of the plasma membrane lipids. Density shift e...
متن کاملATP-dependent cadmium transport by the cadA cadmium resistance determinant in everted membrane vesicles of Bacillus subtilis.
Resistance to cadmium conferred by the staphylococcal plasmid pI258 occurs by means of energy-dependent efflux, resulting in decreased intracellular accumulation of cadmium. Recent sequence information suggested that efflux is mediated by a P-type ATPase. The cadA gene was previously expressed in Bacillus subtilis, conferring resistance to cadmium. Everted membrane vesicles were prepared from B...
متن کاملMechanisms of active transport in isolated bacterial membrane vesicles. Further studies on amino acid transport in Staphylococcus aureus membrane vesicles.
Active amino acid transport in Stajhylococcus aureus U-71 membrane vesicles is coupled to either cy-glycerol phosphate dehydrogenase or L-lactate dehydrogenase depending upon the growth conditions of the parent cells. Vesicles prepared from cells grown on gluconate as a primary carbon source exhibit an absolute specificity for a-glycerol phosphate as a physiological electron donor for transport...
