  • GO:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
  • GO:0016989 The function of binding to a sigma factor and stopping, preventing or reducing the rate of its transcriptional activity.
  • GO:0042121 The chemical reactions and pathways resulting in the formation of alginic acid, a hydrophilic polysaccharide occurring in, for example, the cell walls of brown algae (brown seaweeds).
  • GO:0032885 Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of polysaccharides.
