Co-regulation of AS and eNOS phosphorylation by calcium 1 Protein Kinase C α Phosphorylates a Novel Argininosuccinate Synthase Site at Serine 328 During Calcium-Dependent Stimulation of Endothelial Nitric Oxide Synthase in Vascular Endothelial Cells*

Endothelial nitric oxide synthase (eNOS) utilizes L-arginine as its principal substrate, converting it to L-citrulline and nitric oxide (NO). L-citrulline is recycled to L-arginine by two enzymes, argininosuccinate synthase (AS) and argininosuccinate lyase (AL), providing the substrate arginine for eNOS and NO production in endothelial cells. Together, these three enzymes, eNOS, AS and AL, make...

Cyclin-dependent kinase 5 phosphorylates endothelial nitric oxide synthase at serine 116.

Nitric oxide (NO) production in endothelial cells (EC) is regulated by multisite phosphorylation of specific serine and threonine residues in endothelial NO synthase (eNOS). Among these, eNOS-Ser116 is phosphorylated in the basal state, and its phosphorylation contributes to basal NO production. Here, we investigated the mechanism by which eNOS-Ser116 is phosphorylated during the basal state us...

Inhibitor-κB kinase attenuates Hsp90-dependent endothelial nitric oxide synthase function in vascular endothelial cells.

Endothelial nitric oxide (NO) synthase (eNOS) is the predominant isoform that generates NO in the blood vessels. Many different regulators, including heat shock protein 90 (Hsp90), govern eNOS function. Hsp90-dependent phosphorylation of eNOS is a critical event that determines eNOS activity. In our earlier study we demonstrated an inhibitor-κB kinase-β (IKKβ)-Hsp90 interaction in a high-glucos...

EXPRESSION OF INDUCIBLE NITRIC OXIDE SYNTHASE GENE (iNOS) STIMULATED BY HYDROGEN PEROXIDE IN HUMAN ENDOTHELIAL CELLS

Inducible nitric oxide synthase (iNOS) gene expresses a calcium calmudolin-independent enzyme which can catalyse NO production from L-arginine. The induction of iNOS activity has been demonstrated in a wide variety of cell types under stimulation with cytokines and lipopoly saccharide (LPS). Previous studies indicated that all nitric oxide synthases (NOS) activated in human umbilical vein endot...

AMP-activated protein kinase functionally phosphorylates endothelial nitric oxide synthase Ser633.

Endothelial nitric oxide synthase (eNOS) plays a central role in maintaining cardiovascular homeostasis by controlling NO bioavailability. The activity of eNOS in vascular endothelial cells (ECs) largely depends on posttranslational modifications, including phosphorylation. Because the activity of AMP-activated protein kinase (AMPK) in ECs can be increased by multiple cardiovascular events, we ...
