General annotation (Comments)

Function	Acyl-CoA thioesterases are a group of enzymes that catalyze the hydrolysis of acyl-CoAs to the free fatty acid and coenzyme A (CoASH), providing the potential to regulate intracellular levels of acyl-CoAs, free fatty acids and CoASH. May play an important physiological function in brain. May play a regulatory role by modulating the cellular levels of fatty acyl-CoA ligands for certain transcription factors as well as the substrates for fatty acid metabolizing enzymes, contributing to lipid homeostasis. Has broad specificity, active towards fatty acyl-CoAs with chain-lengths of C8-C18.
Catalytic activity	Palmitoyl-CoA + H2O = CoA + palmitate.
Subcellular location	Cytoplasm.
Tissue specificity	Isoform 1 is expressed constitutively in brain and testis. Isoform 2 is induced in liver by treatment with the peroxisome proliferator.
Post-translational modification	The N-terminus is blocked.
Sequence similarities	Contains 2 acyl coenzyme A hydrolase domains.
Caution	These proteins have been named according to their molecular weight (see Ref.8): BACH (also called CTE-IIa and CTE-II), LACH1 (also called MTE-II) and ACT (also called CTE-IIb). It is unknown whether ACT corresponds to another isoform.
Biophysicochemical properties	Kinetic parameters: KM=5.9 µM for palmitoyl-CoA Vmax=553 µmol/min/mg enzyme with palmitoyl-CoA as substrate
