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 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 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 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 aggregation, arrangement and bonding together of a set of components, including (phenyl)phthiocerol, phthiodiolone, phthiotriol dimycocerosate and diphthioceranate, to form the DIM/DIP layer of the Actinobacterium-type cell wall.

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

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of deprivation of iron ions.

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 chemical reactions and pathways resulting in the formation of secondary metabolites, the compounds that are not necessarily required for growth and maintenance of cells, and are often unique to a taxon.

The chemical reactions and pathways involving L-methylmalonyl-CoA, the L-enantiomer of 2-carboxypropanoyl-CoA. S-methylmalonyl-CoA is an intermediate in the beta oxidation of odd-numbered fatty acids in animals.

A cellular process that results in the biosynthesis of constituent macromolecules, assembly, and arrangement of constituent parts of a cell wall of the type found in Actinobacteria. The cell wall is the rigid or semi-rigid envelope lying outside the cell membrane. Actinobacterial cell walls contain characteristic mycolic acids, of which some are covalently linked to the cell wall peptidoglycan and others accumulate at the cell surface.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal, most prokaryotic cells and some protozoan parasites, maintaining their shape and protecting them from osmotic lysis. In plants it is made of cellulose and, often, lignin; in fungi it is composed largely of polysaccharides; in bacteria it is composed of peptidoglycan; in protozoan parasites such as Giardia species, it's made of carbohydrates and proteins.
