Amino Acid recycling in relation to protein turnover
1School of Biological Sciences, University of East Anglia, Norwich NR4 7TJ, United Kingdom.
Abstract:
Methods of measuring amino acid recycling in Lemna minor are described. The extent to which the recycling of individual amino acids may underestimate protein turnover has been measured for a number of amino acids. The methods have been used to study the relationship between protein turnover and amino acid recycling during nitrogen starvation. It is concluded that following the removal of nitrate from the environment, protein turnover is enhanced, the partitioning of amino acids between protein synthesis and amino acid metabolism is relatively constant, but the total amount of amino acids recycling is increased.
