General Information

| 3.5.99.7 | physiological function | one of the key mechanisms of the effect of bacteria on plant growth and development is their ability to reduce the level of ethylene due to the activity of 1-aminocyclopropanex021-carboxylate deaminase (ACCD). This enzyme catalyzes the hydrolysis of 1-aminocyclopropanex021-carboxylate (ACC), which is an immediate precursor in ethylene biosynthesis, to 2-oxobutyrate and ammonium ions. ACCDx02possessing bacteria contribute to the enhancement of plant resistance to such negative impacts as drought, soil salinity, heavy metal pollution, and the presence of phytopathogens. Amycolatopsis methanolica is a freex02living soil bacterium, apparently not directly associated with plant surface | Amycolatopsis methanolica |
