oksidaz
Oksidaz, or oxidase in English, designates a group of enzymes that catalyze oxidation–reduction reactions in which molecular oxygen (O2) is the terminal electron acceptor. The term is used in several languages (spelled oksidaz, oksydaza, oksidase, etc.) and generally refers to enzymes that remove electrons from substrates and transfer them to O2, yielding water or hydrogen peroxide.
Oxidases are a subset of oxidoreductases and include a wide range of enzymes, often categorized by their
Distinctions: oxidases typically transfer electrons from the substrate to O2 without incorporating oxygen into the substrate,
Applications: oxidases are used in clinical tests (oxidase test for bacterial identification), biosensors, and industrial biocatalysis.
