General annotation (Comments)

Catalytic activity

Acyl-CoA + acetyl-CoA = CoA + 3-oxoacyl-CoA.

Pathway

Lipid metabolism; fatty acid metabolism.

Subunit structure

Homodimer.

Subcellular location

Peroxisome.

Induction

Peroxisomal thiolase is markedly induced (at the level of transcription) by various hypolipidemic compounds in parallel with the other two enzymes of the peroxisomal beta-oxidation system.

Sequence similarities

Belongs to the thiolase family.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: P21775-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: P21775-2)

The sequence of this isoform differs from the canonical sequence as follows:
     334-424: LTVNDIDIFE...AAAVFEYPGN → PLLCGEAGNS...RSKAGGHAAQ
