The chemical reactions and pathways resulting in many of the chemical changes of compounds that are not necessarily required for growth and maintenance of cells, and are often unique to a taxon. In multicellular organisms secondary metabolism is generally carried out in specific cell types, and may be useful for the organism as a whole. In unicellular organisms, secondary metabolism is often used for the production of antibiotics or for the utilization and acquisition of unusual nutrients.

The chemical reactions and pathways resulting in the formation of sterigmatocystin, a carcinogenic mycotoxin produced in high yields by strains of the common molds.

The chemical reactions and pathways resulting in the formation of a pigment, any general or particular coloring matter in living organisms, e.g. melanin.

The chemical reactions and pathways resulting in the formation of o-orsellinic acid.

The chemical reactions and pathways resulting in the formation of monodictyphenone.

The chemical reactions and pathways resulting in the formation of a fatty acid, any of the aliphatic monocarboxylic acids that can be liberated by hydrolysis from naturally occurring fats and oils. Fatty acids are predominantly straight-chain acids of 4 to 24 carbon atoms, which may be saturated or unsaturated; branched fatty acids and hydroxy fatty acids also occur, and very long chain acids of over 30 carbons are found in waxes.

The chemical reactions and pathways resulting in the formation of polyketides, any of a diverse group of natural products synthesized via linear poly-beta-ketones, which are themselves formed by repetitive head-to-tail addition of acetyl (or substituted acetyl) units indirectly derived from acetate (or a substituted acetate) by a mechanism similar to that for fatty acid biosynthesis but without the intermediate reductive steps.

The chemical reactions and pathways resulting in the formation of melanins, pigments largely of animal origin. High molecular weight polymers of indole quinone, they are irregular polymeric structures and are divided into three groups: allomelanins in the plant kingdom and eumelanins and phaeomelanins in the animal kingdom.

The chemical reactions and pathways involving biological pigments e.g. melanin, occurring as part of the development of an organ or organism.

The chemical reactions and pathways resulting in the formation of emericellamide.

The chemical reactions and pathways resulting in the formation of an unsaturated fatty acid, any fatty acid containing one or more double bonds between carbon atoms.

The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.

The biosynthetic process in which peptide bond formation occurs in the absence of the translational machinery. Examples include the synthesis of antibiotic peptides, and glutathione.

The chemical reactions and pathways leading to the formation of macrolides, any of a large group of polyketide compounds that contain a large lactone ring with few or no double bonds and no nitrogen atoms, linked glycosidically to one or more sugar groups. The macrolides include the carbomycins, the erythromycins, oleandomycin, oligomycins, and the spiramycins, and act as antibiotics, mainly against Gram-positive bacteria.

The increase in size or mass of an entire organism, a part of an organism or a cell.

The aggregation, arrangement and bonding together of a set of components to form an asexual spore wall, the specialized envelope lying outside the cell membrane of a spore derived from an asexual process. Examples of this process are found in Bacterial and Fungal species.

Any process that results in a change in state or activity of the symbiont or its cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of detecting molecules of its host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction.
