Characteristics of the protein coding sequence
Acetohydroxyacid synthase

The acetolactate synthase enzyme (ALS) plays a key role in the biochemical pathways of the branched-chain amino acids leucine, isoleucine and valine. The application of ALS-inhibiting herbicides blocks this synthesis pathway. Lack of the aforementioned amino acids interferes with protein synthesis, causing the plant to die off.This gene encodes a modified acetolactate synthase, which confers tolerance to several acetolactate synthase-inhibiting herbicides such as, for example, sulfonylurea.
