1.5.3.23 metabolism strain CB4 degrades glyphosate along two concurrent pathways to aminomethylphosphonate, glyoxylate, sarcosine, glycine and formaldehyde as products, i.e. by the C-P lyase activity and the glyphosate oxidoreductase activity 1.5.3.23 physiological function a rapid decrease of the concentration of aminomethylphosphonate resulting from the glyphospate cleavage is observed in the presence of pyridoxal 5'-phosphate and pyruvate. aminomethylphosphonate: pyruvate aminotransferase, is the second enzyme of the proposed phosphonatase pathway of glyphosate transformation. Glyphospate metabolism in Ochrobactrum anthropi GPK 3 is accompanied by intracellular formation of formaldehyde 1.5.3.23 physiological function Geobacillus caldoxylosilyticus is able to utilize a number of organophosphonates as the sole phosphorus source for growth at 60°C. During growth on glyphosate, aminomethylphosphonate release to the medium is observed 1.5.3.23 physiological function glyphosate degradation can follow different pathways depending on physiological characteristics of metabolizing strains. In Ochrobactrum anthropi GPK3 the initial cleavage reaction is catalyzed by glyphosate oxidoreductase with the formation of aminomethylphosphonic acid and glyoxylate, whereas Achromobacter sp. MPS12 utilize C-P lyase, forming sarcosine 1.5.3.23 physiological function in Ochrobactrum sp., glyphosate (3 mM) degradation is induced by phosphate starvation, and is completed within 60 h. Aminomethylphosphonic acid is detected in the exhausted medium. The bacterium grows even in the presence of glyphosate concentrations as high as 200 mM
