How nutrients influence it

Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.

How nutrients reach it in more than one step

Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What acts on it

  1. Purified GLYAT formed N-isovalerylglycine from isovaleryl-CoA and glycine in vitro, with lower affinity than for its preferred substrate.

  2. Purified GLYATL1 also supported N-isovalerylglycine formation in vitro, less favorably than its preferred substrate reaction.
