| 2-methylacetoacetyl-CoA thiolase | <enzyme> An enzyme that is part of the l-isoleucine degradation pathway; it catalyses the conversion of 2-methylacetoacetyl-CoA (CH3COCH(CH3)COSCoA) to acetyl-CoA and propionyl-CoA. A deficiency of this enzyme leads to an accumulation of 2-methylacetoacetyl-CoA, causing episodes of severe metabolic acidosis and ketosis. (05 Mar 2000) |
