Structural basis and evolutionary pathways of glycerol-1-phosphate transport in marine bacteria

Proceedings of the National Academy of Sciences, Volume 122, Number 50, December 2025.
Significance Archaea contribute substantially to global marine biomass, but how their unique membrane building block, glycerol-1-phosphate, is recycled has remained unexplored. This study identifies two distinct bacterial transport systems, GpxB and UgpB,…
