WebJul 9, 2024 · This defines an anaerobic methylthio-alkane reductase methionine synthesis pathway and establishes the role of a nitrogenase-like enzyme system in sulfur metabolism (Fig. 1A, red box). Sulfur metabolism is evidently the primary function of these nitrogenase-like methylthio-alkane reductases, as opposed to nitrogen fixation by nitrogenase.
WebEthylene is a gaseous phytohormone and the first of this hormone class to be discovered. It is the simplest olefin gas and is biosynthesized by plants to regulate plant development, growth, and stress responses via a well-studied signaling pathway.
