Complexation With Chromium Makes an Nonutilizable Amino Acid Lysine into a Utilizable Form in S. cerevisiae (NCIM 3558) Through Changes in Intracellular Compartmentation of the Amino Acid

K. S. Karthikeyan, K. Sivarama Sastry


The present study deals with the complete reversion of the utilizability of an otherwise nonutilizable L-amino acid herein L-lysine in Saccharomyces cerevisiae NCIM 3558 on complexation with chromium sulfate hexahydrate. It is observed for the first time that following complexation of all the inhibitory effect of L-lysine on yeast is completely reversed, and the detailed mechanism is discussed and the mechanism of action is dealt in detail.
