Like a relay racer: The protein PEX39 (purple) carries enzymes (yellow) like a baton to the peroxisomes. There, the cargo is transported through the membrane by another PEX protein. (Image: Daniel Wendscheck / University of Würzburg)

#Biochemistry: #PEX39, a newly discovered #peroxin protein, transports enzymes into #peroxisomes like a relay racer. New paper @natcellbio.nature.com – congratulations to @dwendscheck.bsky.social @warscheidlab.bsky.social et al!
