Tetrahydrobiopterin in nitric oxide synthase [PDF]
IUBMB Life, 2013 AbstractSummary: Nitric oxide synthase (NOS) is a critical enzyme for the production of the messenger molecule nitric oxide (NO) from L‐arginine. NOS enzymes require tetrahydrobiopterin as a cofactor for NO synthesis. Besides being one of the few enzymes to use this cofactor, the role of tetrahydrobiopterin in NOS catalytic mechanism is different from ...

Nitric Oxide synthases and atrial fibrillation [PDF]
Frontiers in Physiology, 2012 Oxidative stress has been implicated in the pathogenesis of atrial fibrillation. There are multiple systems in the myocardium which contribute to redox homeostasis, and loss of homeostasis can result in oxidative stress.

Neuronal Nitric Oxide Synthase
, 2017 Nitric oxide synthase (NOS), a flavo‐hemoprotein, regulates nitric oxide (NO) synthesis that has dual biological activities: as an important signalling molecule in vasodilatation and neurotransmission at low concentrations and at higher concentrations as

Nitric oxide in liver fibrosis: The role of inducible nitric oxide synthase [PDF]
Clinical and Molecular Hepatology, 2015 The inducible form of nitric oxide synthase (iNOS) is expressed in hepatic cells in pathological conditions. Its induction is involved in the development of liver fibrosis, and thus iNOS could be a therapeutic target for liver fibrosis.

The Effect of Pneumonic Pasteurellosis on Apoptosis and Nitric Oxide Synthase in the Lungs in Calves
Turkish Journal of Agriculture: Food Science and Technology, 2020 Pneumonic Pasteurellosis (PP) is an infectious disease caused by Pasteurella multocida and Mannheimia haemolytica, mostly observed in cattle, sheep and calves. PP is characterized by fibrinous bronchopneumonia and pleuritis in the lungs.

Nitric oxide-dependent activation of CaMKII increases diastolic sarcoplasmic reticulum calcium release in cardiac myocytes in response to adrenergic stimulation. [PDF]
PLoS ONE, 2014 Spontaneous calcium waves in cardiac myocytes are caused by diastolic sarcoplasmic reticulum release (SR Ca(2+) leak) through ryanodine receptors.

Metabolism via Arginase or Nitric Oxide Synthase: Two Competing Arginine Pathways in Macrophages
Frontiers in Immunology, 2014 Macrophages play a major role in the immune system, both as antimicrobial effector cells and as immunoregulatory cells, which induce, suppress or modulate adaptive immune responses.
