In the field of enzymology, murburn is a term coined by Kelath Murali Manoj that explains the catalytic mechanism of certain redox-active proteins. The term describes the equilibrium among molecules, unbound ions and radicals, signifying a process of "mild unrestricted redox catalysis".
In the left panel, molecular interactions involved in murburn concept are shown. A murzyme may use (generate/modulate/stabilize/utilize) DRS, which may enter into interactive equilibriums with diverse or select molecules and ions in milieu, giving rise to catalytic electron or moiety transfers, including posttranslational modifications (PTMs) of auto or hetero proteins. The central panel shows the overall systemic or macroscopic physiological overview of ECS-initiated murburn in cells leading to their functioning as SCEs. Methane (CH
Catalysis is the increase in rate of a chemical reaction due to an added substance known as a catalyst. Catalysts are not consumed by the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; mixing, surface area, and temperature are important factors in reaction rate. Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process of regenerating the catalyst.

An air filter that uses a low-temperature oxidation catalyst to convert carbon monoxide to less toxic carbon dioxide at room temperature. It can also remove formaldehyde from the air.
Zeolites are extruded as pellets for easy handling in catalytic reactors.
Typical vanadium pentoxide catalyst used in sulfuric acid production for an intermediate reaction to convert sulfur dioxide to sulfur trioxide.
