PMCID: PMC1066914  PMID: 16663628

Abstract

The activity of the first enzyme of the shikimate pathway, 3-deoxy-d-arabino-heptulosonate 7-phosphate synthase, is demonstrated in extracts of Daucus carota cells grown in suspension culture. Maximum specific enzyme activity is found midway through the logarithmic growth of the culture; cells in lag and stationary phases of growth have lower enzyme levels. The enzyme is activated by tyrosine and tryptophan. The extent of activation varies during cell growth.
