PROTEIN SYNTHESIS IN PLANTS

Abstract
Summary: The final stages in the formation of protein, rather than the formation of amino‐acids, are discussed. The approach is physiological rather than biochemical. After reviewing the present state of knowledge of the structure of proteins various suggestions as to the substances used in the formation of the protein are considered. The evidence seems to be in favour of the formation by condensation of amino‐acids rather than by the polymerization of some simple unit. This leads to a consideration of the various seats of synthesis in the cell and to the mechanism by which the proteins are formed from their constituent parts. The article concludes with a discussion of the interrelation of nitrogen metabolism and respiration and of the factors governing amino‐acid formation and protein synthesis.
