In cells, excess of metabolic fuel is converted into fatty acids in cytosol and oxidized later in mitochondria to generate ATP and acetyl-CoA.
In fatty acid synthesis, catalytic formation of malonyl-CoA (precursor for long-chain fatty acyl-CoA, LCFA-CoA) from acetyl-CoA by Acetyl-CoA carboxylase (ACC-1) is the rate limiting step.
The translocation of LCFA-CoA from cytosol to mitochondria, catalyzed by two carnitine palmitoyl transferases (CPT-1 & CPT-2) and regulated by ACC-2, is the rate limiting step of mitochondrial fatty acid ?-oxidation.
Activities of ACC-1, ACC-2 and other key proteins of carbohydrate and fat metabolism are regulated by their phosphorylation by 5'-AMP-activated protein kinase (AMPK).
AMPK switches-off biosynthetic processes when ATP levels are depleted and AMP rises in response to fuel deficiency and treatments like heat shock, ischaemia and exercise.
A defect in AMPK switch leads to insulin resistance, dyslipidemia, ketosis resistance and other metabolic derangements in Type 2 diabetes.
AMPK also regulates cholesterol biosynthesis via phosphorylation and inactivation of hormone-sensitive lipase and hydroxymethylglutaryl-CoA resuctase.
It also appears to act as a metabolic stress-sensing protein kinase switching off biosynthetic pathway when ATP levels are depleted and when 5-AMP rises in response to fuel limitation and or hypoxia.
