Energy coupling in bacterial periplasmic permeases.
Bacterial active transport systems (permeases) can be broadly divided into two classes with regard to their mechanism of energy coupling: those energized by electrochemical ion gradients and those energized by substrate-level phosphorylation. The distribution of the permeases according to this classification is matched by their fundamentally different characteristics. Electrochemical ion gradie...

workers (Dalbadie-McFarland et al., 1982). M 13 derivatives have the advantage of ease of preparation of singlestranded substrate for the priming reaction. However, insofar as plasmids may be nicked and gapped under the appropriate conditions, single-stranded regions of genes cloned in plasmids can also be mutagenized using the primer-directed method. The first change we hope to make is a C to ...

متن کاملBacterial Periplasmic Binding Proteins
The cell envelope of gram-negative bacteria includes inner and outer membranes with the periplasmic space in between. The transport systems for many nutrients in these organisms include components in both the periplasm and the inner membrane. In some cases, e.g., maltose, transport components in the outer membrane are also involved. The scope of this review will be limited to a progress report ...
متن کاملBeta-galactoside transport in bacterial membrane preparations: energy coupling via membrane-bounded D-lactic dehydrogenase.
The transport of beta-galactosides by isolated membrane preparations from Escherichia coli strains containing a functional y gene is markedly stimulated by the conversion of D-lactate to pyruvate. The addition of D-lactate to these membrane preparations produces a 19-fold increase in the initial rate of uptake and a 10-fold stimulation of the steady-state level of intramembranal lactose or thio...
