Lipid Droplet Targeting Drives Substrate Access during Very Long Chain Fatty Acid Activation by Fat1

Carolin Willner, Jennifer L. Sapia, Bianca M. Esch, Pia Erdbrügger, Lisa Kauffmann, Alicia Damm, Sergej Limar, Sebastian Eising, Stefan Walter, Abdou Rachid Thiam, Carolin Körner, Stefano Vanni, Florian Fröhlich

This study shows lipid droplets are the site of VLCFA activation by Fat1, with Fat1 targeting LDs via an amphipathic helix and using a hydrophobic cavity to access substrates.

Uptake of exogenous serine is important to maintain sphingolipid homeostasis in Saccharomyces cerevisiae

Bianca M. Esch, Sergej Limar, André Bogdanowski, Christos Gournas, Tushar H. More, Celine Sundag, Stefan Walter, Jürgen J. Heinisch, Christer S. Ejsing, Bruno André, Florian Fröhlich

This study shows that serine uptake via Gnp1 is critical for maintaining sphingolipid homeostasis in yeast by linking serine import to sphingolipid biosynthesis.
