Control of isoleucine, valine, and leucine biosynthesis.
Product activation of yeast threonine dehydratase by ammonia.
A form of this enzyme present predominantly in younger leaves is considered to be the "biosynthetic" form of the enzyme because it is feedback inhibited by isoleucine.
Saccharomyces cerevisiae valine biosynthesis
Biofilm: complex aggregation of microorganisms marked by the excretion of a protective and adhesive matrix. Cropping: refers to the removal of the yeast which has settled to the bottom of the fermenter at the end of the fermentation. Cropped yeast can either be discarded, stored or re-used straight away.

We will consider one important step in the synthesis of this group of 3 aminoacids, namely the step in which homocysteine is converted to methionine,catalyzed by the enzyme :

Use of the valine biosynthetic pathway to convert glucose into ..
has 3 isozymes of aspartokinase that respond differently toeach of the 3 amino acids, with regard to enzyme inhibition and feedbackinhibition. The biosynthesis of lysine, methionine and threonine are not, then,controlled as a group.
