Characteristics of the protein coding sequence
Acetohydroxy acid Synthase
EN
Acetohydroxy acid synthase (also known as acetolactate synthase)  is a key enzyme that catalyzes the first common step in the biosynthesis of the essential branched-chain amino acids isoleucine, leucine, and valine

The gm-hra gene has been modified by site directed mutagenesis (P183A and W560L) from the native soybean als gene and encodes a version of the enzyme that is tolerant to als inhibitors such as sulfonylurea herbicide.

It also contains 15 additional nucleotides from the native als gene 5'UTR.
