Catalysis of the reaction: GDP-6-deoxy-D-mannose + NAD(P)+ = GDP-4-dehydro-6-deoxy-D-mannose + NAD(P)H + H+. In the reverse reaction, a mixture of GDP-D-rhamnose and its C-4 epimer is formed.

The chemical reactions and pathways resulting in the breakdown of L-fucose (6-deoxy-Lgalactose).

The formation of GDP-L-fucose from L-fucose, without de novo synthesis. L-fucose is phosphorylated by fucokinase and then converted by fucose-1-phosphate guanylyltransferase (EC:2.7.7.30).

The chemical reactions and pathways resulting in the formation of GDP-L-fucose, a substance composed of L-fucose in glycosidic linkage with guanosine diphosphate.

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).

Any process that activates or increases the frequency, rate or extent of pectin catabolic process.

Any process that modulates the frequency, rate or extent of pectin catabolic process.

The orientation of free radical substrates in such a way that only a particular stereoisomer is synthesized by an enzyme. Best characterized as a function during lignan biosynthesis.

Any process that stops, prevents or reduces the frequency, rate or extent of pectin catabolic process.

Any process that activates or increases the frequency, rate or extent of phosphatidylethanolamine metabolic process.

Any process that modulates the frequency, rate or extent of phosphatidylethanolamine metabolic process.

Any process that stops, prevents or reduces the frequency, rate or extent of phosphatidylethanolamine metabolic process.

Any process that modulates the frequency, rate or extent of cellulose biosynthetic process.

The chemical reactions and pathways resulting in the breakdown of indole glucosinolates, sulfur-containing compounds that have a common structure linked to an R group derived from tryptophan.
