REGULATION OF ENZYME ACTIVITY BY SPECIFIC  REVERSAL OF FEEDBACK INHIBITION.
Studies with a photosynthetic bacterium have revealed a novel type of regulatory control of enzymes participating in amino acid biosyntheses. Feeback inhibition of enzyme activity can be specifically reversed by ultimate end products of a branched pathway.
