POLYPEPTIDE HAVING GLYOXYLASE III ACTIVITY, POLYNUCLEOTIDE ENCODING THE SAME AND USES THEREOF

摘要

The present invention relates to a novel polypeptide having the enzymatic activity of conversion of methylglyoxal to lactic acid in a single step (known as glyoxalase III activity), a polynucleotide having a nucleotide sequence encoding such polypeptide and uses thereof. Theinvention relates to the modulation of the glyoxalase III activityin a microorganism by varying the expression level of the polynucleotide coding for such polypeptide.The invention also relates to the production of commodity chemicals, especially 1,2-propanediol, acetol, and lactic acid by fermenting microorganisms wherein their glyoxalase III activity is modulated.
