Fucose metabolism pathways are present in many bacterial species and typically contain the central fucose-processing enzymes fucose isomerase (FcsI), fuculose kinase (FcsK), and fuculose-1-phosphate aldolase (FcsA). Fucose initially undergoes isomerization by FcsI producing fuculose, which is then phosphorylated by FcsK.
