Adenosine 5'-triphosphate synthesis driven by a protonmotive force in membrane vesicles of Escherichia coli.

abstract：:Marinobacter hydrocarbonoclasticus DSM 8798 has been reported to synthesize isoprenoid wax ester storage compounds when grown on phytol as the sole carbon source under limiting nitrogen and/or phosphorous conditions. We hypothesized that isoprenoid wax ester synthesis involves (i) activation of an isoprenoid fatty aci...
