Protein attributes
| Sequence length | 723 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Catalytic activity | (3S)-3-hydroxyacyl-CoA = trans-2(or 3)-enoyl-CoA + H2O. (3Z)-dodec-3-enoyl-CoA = (2E)-dodec-2-enoyl-CoA. (S)-3-hydroxyacyl-CoA + NAD+ = 3-oxoacyl-CoA + NADH. |
| Enzyme regulation | Enzyme activity enhanced by acetylation. Ref.11 |
| Pathway | |
| Subunit structure | Monomer. |
| Subcellular location | |
| Tissue specificity | Liver and kidney. Lower amounts seen in the brain. Ref.1 |
| Post-translational modification | Acetylated, leading to enhanced enzyme activity. Acetylation is enhanced by up to 80% after treatment either with trichostin A (TSA) or with nicotinamide (NAM) with highest increase on Lys-346. Acetylation and enzyme activity increased by about 1.5% on addition of fatty acids. |
| Miscellaneous | Absent in patients suffering with peroxisomal disorders such as Zellweger syndrome, neonatal adrenoleukodystrophy and infantile Refsum disease. |
| Sequence similarities | In the N-terminal section; belongs to the enoyl-CoA hydratase/isomerase family. In the C-terminal section; belongs to the 3-hydroxyacyl-CoA dehydrogenase family. |
