GENETIC TRANSFER OF STREPTOMYCIN AND AMINOPROPANOLSTREPTOMYCIN RESISTANCE.

abstract：:MinD binds to phospholipid vesicles in the presence of ATP and is released by MinE, which stimulates the MinD ATPase. Membrane binding requires a short conserved C-terminal region, which has the potential to form an amphipathic helix. This finding has led to a model in which the binding of ATP regulates the formation ...
