| Common Name | Glutarate semialdehyde |
|---|
| Description | In the lysine degradation IV pathway, glutarate semialdehyde reacts with NADP+ and H2O to produce glutarate, NADPH, and H+. In this pathway, glutarate semialdehyde is produced by the reaction between 5-aminopentanoate and 2-ketoglutarate, with L-glutamate as a byproduct. The enzyme responsible for this reaction is 5-aminovalerate aminotransferase. In the lysine degradation III pathway, glutarate semialdehyde reacts with NAD+ and H2O to produce glutarate and NADH. In this pathway, glutarate semialdehyde is produced by the reaction between 5-aminopentanoate and 2-ketoglutarate, with L-glutamate as a byproduct. The enzyme responsible for this reaction is 5-aminovalerate aminotransferase. |
