| Accepted name: |
3-[(3aS,4S,7aS)-7a-methyl-1,5-dioxo-octahydro-1H-inden-4-yl]propanoate—CoA ligase |
| Reaction: |
ATP + 3-[(3aS,4S,7aS)-7a-methyl-1,5-dioxo-octahydro-1H-inden-4-yl]propanoate + CoA = AMP + diphosphate + 3-[(3aS,4S,7aS)-7a-methyl-1,5-dioxo-octahydro-1H-inden-4-yl]propanoyl-CoA |

| Glossary: |
3-[(3aS,4S,7aS)-7a-methyl-1,5-dioxo-octahydro-1H-inden-4-yl]propanoate = HIP |
| Other name(s): |
fadD3 (gene name); HIP—CoA ligase |
| Systematic name: |
3-[(3aS,4S,7aS)-7a-methyl-1,5-dioxo-octahydro-1H-inden-4-yl]propanoate:CoA ligase (AMP-forming) |
| Comments: |
The enzyme, characterized from actinobacterium Mycobacterium tuberculosis, catalyses a step in the degradation of cholesterol and cholate. The enzyme is very specific for its substrate, and requires that the side chain at C17 is completely removed. |
