A biotinyl-protein. Also catalyses transcarboxylation; the plant enzyme also carboxylates propanonyl-CoA and butanoyl-CoA.

Rate-limiting Description

"However, since it is unknown whether peroxisome proliferators have an effect on biosynthesis of fatty acid or not, we commenced to study if acetyl-CoA carboxylase, the rate-limiting enzyme of fatty acid biosynthesis, is inhibited by 2-(p-chlorophenoxy)-2-methylpropionic acid or 2-ethylhexanoic acid which is a typical peroxisome proliferator."

Regulatory Information

Upstream transcription factor


Regulatory type




transcriptional factor;PPARgamma(19016)

"when fed fat-free diet for 10 days, there was significant up-regulation of PPARgamma and several enzymes in the lipogenic pathway in the liver of liver-specific ACC1 knockout mice compared with the WT mice" (16717184)
