an evolutionarily conserved protein FucU (Fucose, Unknown) is a close paralogue of RbsD, with any compared pair of RbsD and FucU homologues sharing about 20% amino acid sequence identity with each other. —so says the study “Crystal Structures of RbsD Leading to the Identification of Cytoplasmic Sugar-binding Proteins with a Novel Folding Architecture,” Min-Sung Kim, […]
