1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
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.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
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 it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
Where it participates (unsigned role)
Human AMT transfers the aminomethyl-lipoyl intermediate's carbon to tetrahydrofolate, yielding 5,10-methylene-THF, ammonia and reduced H-protein.
Experimental context and source evidence
- cross_nutrient
- B6-dependent GLDC precedes lipoyl-carrier transfer and folate-dependent AMT chemistry.
- experimental_model
- Purified human AMT structures and mutational analyses
- limitations
- AMT is the directly examined human enzyme; this study did not test dietary B6 depletion or the entire pathway flux.
- nutrient_topic
- Vitamin B6 research collection; topical membership is not evidence of a direct dietary effect. · Vitamin B6
- organism
- Homo sapiens
- plain_language
- Glycine cleavage connects its B6-dependent first step to a separate folate-dependent step.
