Dihydroxyhexanoic acid biosynthesis controls turgor in pathogenic fungi

Check out this cool #cryo-EM study spearheaded by our neighbor @tafurlab.bsky.social and his colleagues! A must-read for anyone interested in the molecular mechanisms governing (m)TORC1 regulation. Congrats to all involved! 🎉
It took a while but it’s finally published!
The GAP activity of SEAC (GATOR) is a metabolic switch that allows cells to quickly respond to changes in amino acid levels, both for inhibition and reactivation.
