L-fucopyranose is an important monosaccharide found in a diverse array of organisms. It is a carbohydrate component of bacterial lipopolysaccharides, mammalian and plant glycoproteins (such as the human antigenic glycoproteins or glycolipids of erythrocyte membranes) and various plant cell wall polysaccharides. It is found in xyloglucans and rhamnogalacturonans I and II. Fucosylation is performed by fucosyltransferases which require the activated form GDP-L-fucose (GDP-Fuc) as the donor substrate.
The formation of GDP-L-fucose occurs via two routes: a) a de novo synthesis route from GDP-α-D-mannose (this pathway), and b) a salvage pathway leading to the formation of UDP-Fuc from free L-fucopyranose ( GDP-L-fucose biosynthesis II (from L-fucose)).
Key Notes on the Enzymes:
The de novo synthesis of GDP-Fuc from GDP-D-mannose (GDP-Man) comprises three catalytic steps: a 4,6-dehydration, a 3,5-epimerization, and a 4-reduction. The first reaction step is catalyzed by GDP-mannose 4,6-dehydratase, which involved the formation of the intermediate GDP-4-dehydro-6-deoxy-α-D-mannose. In Arabidopsis thaliana, the MUR1 encodes a protein which was shown to possess this catalytic activity. In bacteria ( Escherichia coli), fungi ( Mortierella alpina), plants ( Arabidopsis thaliana) and humans, the second and third reactions steps have been shown to be catalyzed by a single bifunctional polypeptide: GDP-fucose synthase [Nakayama03, Sullivan98, Tonetti96, Ren10]. The coexpression of Arabidopsis thaliana MUR1 and GER1 (encoding for GDP-4-keto-6-deoxymannose-3,5-epimerase-4-reductase) genes in yeast cells led to the production of GDP-Fuc from GDP-Man [Nakayama03].
