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 is catalyzed by two carnitine palmitoyl transferases (CPT-1 & CPT-2) and regulated by ACC-2, the rate limiting step of mitochondrial fatty acid b-oxidation.
Activities of ACC-1 and 2 are regulated by their phosphorylation by 5'-AMP-activated protein kinase (AMPK).
Diabetes deranges AMPK master-switch and represses the ACC-1 gene-expression and stimulates excessive fatty acid oxidation which in turn interferes with glucose metabolism
Mitochondrial oxidation of LC-FCA is initiated by the sequential action of CPT-1, which is located in the outer membrane, and CPT-2, which is located in the inner membrane together with a carnitine-acylcarnitine translocase.
CPT-2 (mouse/rat/human 658-aa, ~74kD, chromosome 1p32, ~20% identity with CPT1) is a ubiquitous malonyl-CoA-insensitive transferase localized in the inner mitochondrial membrane.
It catalyzes the re-synthesis of acyl-CoA from acyl-carnitines.
CPT-2 deficiency leads to the most commonly inherited, lipid myopathy in adults characterized by exercise-induced pain, stiffness, and myoglobinuria.
The aa sequences of the two isoforms are ~61% identical.
