Chain A   (FCL_ECOLI | P32055)
molecular function
    GO:0050577    GDP-L-fucose synthase activity    Catalysis of the reaction: GDP-L-fucose + NAD+ = GDP-4-dehydro-6-deoxy-D-mannose + NADH + H+.
    GO:0070401    NADP+ binding    Interacting selectively and non-covalently with the oxidized form, NADP+, of nicotinamide-adenine dinucleotide phosphate, a coenzyme involved in many redox and biosynthetic reactions.
    GO:0003824    catalytic activity    Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
    GO:0050662    coenzyme binding    Interacting selectively and non-covalently with a coenzyme, any of various nonprotein organic cofactors that are required, in addition to an enzyme and a substrate, for an enzymatic reaction to proceed.
    GO:0016853    isomerase activity    Catalysis of the geometric or structural changes within one molecule. Isomerase is the systematic name for any enzyme of EC class 5.
    GO:0016491    oxidoreductase activity    Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
biological process
    GO:0042351    'de novo' GDP-L-fucose biosynthetic process    The chemical reactions and pathways resulting in the formation of GDP-L-fucose from GDP-D-mannose via GDP-4-dehydro-6-deoxy-D-mannose, requiring the functions of GDP-mannose 4,6-dehydratase (EC:4.2.1.47) and GDP-L-fucose synthase (EC:1.1.1.271).
    GO:0009242    colanic acid biosynthetic process    The chemical reactions and pathways resulting in the formation of colanic acid, a capsular bacterial polysaccharide.
    GO:0008152    metabolic process    The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
    GO:0009226    nucleotide-sugar biosynthetic process    The chemical reactions and pathways resulting in the formation of nucleotide-sugars, any nucleotide-carbohydrate in which the distal phosphoric residue of a nucleoside 5'-diphosphate is in glycosidic linkage with a monosaccharide or monosaccharide derivative.
    GO:0055114    oxidation-reduction process    A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
