  • GO:0005737 The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
  • GO:0004315 Catalysis of the reaction: acyl-[acyl-carrier protein] + malonyl-[acyl-carrier protein] = 3-oxoacyl-[acyl-carrier protein] + CO2 + [acyl-carrier protein].
  • GO:0016746 Catalysis of the transfer of an acyl group from one compound (donor) to another (acceptor).
  • GO:0033818 Catalysis of the reaction: acetyl-CoA + malonyl-[acyl-carrier protein] = acetoacyl-[acyl-carrier protein] + CoA + CO2.
  • GO:0030497 The elongation of a fatty acid chain by the sequential addition of two-carbon units.
  • GO:0044550 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.
  • GO:0006633 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.
