Abstract
in continuation of our previous study, we show that phosphatidyl ethanolamine (PE) depletion affects, in addition to amino acid transporters, activities of at least two other proton motive force (pmf)-driven transporters (Ura4p and Mal6p). For Can1p, we demonstrate that the lack of PE results in a failure of the permease targeting to plasma membrane. Despite the pleiotropic effect of PE ...
Abstract
in continuation of our previous study, we show that phosphatidyl ethanolamine (PE) depletion affects, in addition to amino acid transporters, activities of at least two other proton motive force (pmf)-driven transporters (Ura4p and Mal6p). For Can1p, we demonstrate that the lack of PE results in a failure of the permease targeting to plasma membrane. Despite the pleiotropic effect of PE depletion, a specific role of PE in secretion of a defined group of permeases can be distinguished. Pmf-driven transporters are more sensitive to the lack of PE than other plasma membrane proteins. (C) 2002 Elsevier Science B.V. All rights reserved.
