WebOne such compound, phosphinothricin tripeptide, contains the unusual amino acid phosphinothricin attached to two alanine residues. Synthetic phosphinothricin (glufosinate) is a component of two top-selling herbicides (Basta and Liberty), and is widely used with resistant transgenic crops including corn, cotton and canola. WebPhosphinothricin-producing Streptomyces spp. also have an enzyme that detoxifies l -phosphinothricin by acylating it. This enzyme is encoded by the bar gene. Bar is the abbreviation of bialaphos resistance. Bialaphos is a GS-inactive tripeptide produced by the same microbe. It is degraded by plants to form l -phosphinothricin. grangemouth obituaries
