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.
What acts on it
The correction assigns mcm5U34 to the housekeeping selenoprotein set.

# Correction first In my last message I labeled the tRNA isoforms backwards. Fixing it, because this one matters: - **mcm⁵U34** (no ribose methyl) → supports **housekeeping** selenoproteins: TXNRD1, GPX4 - **mcm⁵Um34** (ribose methylated) → **required** for the **stress-related** set: GPX1, SELENOW The hierarchy table was right. The labels on the two isoforms were flipped. Um34 is the *added* mark, and it's the one you lose first — which is why the proteins that depend on it die first.
