Initial steps in the degradation of phosphinothricin (glufosinate) by soil bacteria.
Three hundred bacterial isolates from soil were tested for resistance against phosphinothricin [PPT; dl-homoalanin-4-yl(methyl)phosphinic acid], the active ingredient of the herbicide BASTA. Eight resistant bacterial strains and Escherichia coli were analyzed for PPT-transforming activities. At least three different enzymatic reactions could be detected in cell extracts. In six strains an acety...

Stereospecific production of the herbicide phosphinothricin (glufosinate) by transamination: isolation and characterization of a phosphinothricin-specific transaminase from Escherichia coli.
An aminotransferase capable of transaminating 2-oxo-4-[(hydroxy)(methyl)phosphinoyl]butyric acid to L-phosphinothricin [L-homoalanine-4-yl-(methyl)phosphinic acid], the active ingredient of the herbicide Basta (Hoechst AG), was purified to apparent homogeneity from Escherichia coli K-12. The enzyme catalyzes the transamination of L-phosphinothricin and various analogs with 2-ketoglutarate as th...
متن کاملInitial steps in anoxic testosterone degradation by Steroidobacter denitrificans.
Steroid compounds have many important physiological activities in higher organisms. Testosterone and related steroids are important environmental contaminants that disrupt the endocrine systems of animals. The degradation of steroids, especially under anoxic conditions, is challenging because of their complex chemical structure. A denitrifying gamma-proteobacterium, Steroidobacter denitrificans...
متن کاملThe Effect of Phosphinothricin (Glufosinate) on Photosynthesis II. The Causes of Inhibition of Photosynthesis
It was shown in the previous study that phosphinothricin (glufosinate) causes an accumulation of ammonia and inhibition o f photosynthesis. The extent to which there is a connection between these two processes is now investigated in the present study. First of all, the role of N H 3 per se in the impairment of photosynthesis was to be clarified. For this purpose, the inhibition of photosyn the...
