A ubiquitin ligase complex in which a cullin from the Cul1 subfamily and a RING domain protein form the catalytic core; substrate specificity is conferred by a Skp1 adaptor and an F-box protein. SCF complexes are involved in targeting proteins for degradation by the proteasome. The best characterized complexes are those from yeast and mammals (with core subunits named Cdc53/Cul1, Rbx1/Hrt1/Roc1).

Any ubiquitin ligase complex in which the catalytic core consists of a member of the cullin family and a RING domain protein; the core is associated with one or more additional proteins that confer substrate specificity.

Elongation of a fatty acid chain into which two or more C-C double bonds have been introduced.

A protein complex that possesses molybdopterin synthase activity. In E. coli, the complex is a heterotetramer consisting of two MoaD and two MoaE subunits.

The chemical reactions and pathways resulting in the formation of nicotinamide adenine dinucleotide (NAD), beginning with the synthesis of tryptophan or aspartate from simpler precursors; biosynthesis may be of either the oxidized form, NAD, or the reduced form, NADH.

The chemical reactions and pathways resulting in the formation of nicotinamide adenine dinucleotide, a coenzyme present in most living cells and derived from the B vitamin nicotinic acid; biosynthesis may be of either the oxidized form, NAD, or the reduced form, NADH.

OBSOLETE. The aggregation, arrangement and bonding together of strand exchange proteins (recombinases) into higher order oligomers on single-stranded DNA, involved in the conversion of the mating-type locus from one allele to another.

Elongation of a fatty acid chain into which one C-C double bond has been introduced.

Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways by which individual cells transform chemical substances.

Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways involving carbohydrate.

The chemical reactions and pathways resulting in the formation of cytokinins, a class of adenine-derived compounds that can function in plants as growth regulators.

Any cellular process that decreases the rate, extent or frequency of the chemical reactions and pathways involving carbohydrates carried out by repression of transcription.

The chemical reactions and pathways involving ethylene (C2-H4, ethene), a simple hydrocarbon gas that can function in plants as a growth regulator.

The chemical reactions and pathways involving an alkene, any acyclic branched or unbranched hydrocarbon having one carbon-carbon double bond and the general formula CnH2n, as carried out by individual cells.

The chemical reactions and pathways resulting in the formation of nicotinamide adenine dinucleotide (NAD), beginning with the synthesis of aspartate from simpler precursors; biosynthesis may be of either the oxidized form, NAD, or the reduced form, NADH.

OBSOLETE. The chemical reactions and pathways resulting in the formation of cinnamic acid, 3-phenyl-2-propenoic acid, which is then utilized in the metabolism of salicylic acid.
