| Subunit structure | The acetolactate synthase complex contains the catalytic regulatory subunit ILV2 and the regulatory small subunit ILV6. Ref.4 |
| Subcellular location | |
| Miscellaneous | Present with 15800 molecules/cell in log phase SD medium. |
| Sequence similarities | Belongs to the acetolactate synthase small subunit family. Contains 1 ACT domain. |
