Characterization and <i>in planta</i> tolerance of a phosphinothricin acetyltransferase enzyme from <i>Streptomyces coelicolor</i> <scp>A3</scp> (2)

Here we show for the first time that when the DSM-2 trait is transgenically overexpressed in soybean and corn plants, it provides a similar level of herbicide tolerance as other previously characterized PAT or Bar enzymes. Protein structure modeling also supports the conclusion that DSM-2 is in the same protein family as PAT and Bar. As such, although DSM-2 shares little homology from a primary protein sequence standpoint, the trait is still a viable alternative for use in commercial herbicide tolerance programs. © 2026 Society of Chemical Industry.
