Evidence that Ser 1179 is functionally important for Akt-stimulated NO release. COS cells were transfected with plasmids for wild-type eNOS or eNOS mutants, in the absence or presence of Akt, and the expression of the proteins and production of NO (assayed as ) were determined. Constructs with the S1179A mutation were not activated by Akt; the S1179D mutation resulted in a gain of function. Data are mean ± s.e.m. of 4-7 experiments; asterisks represent significant differences (P < 0.05).
