Firefly luciferase is the light-emitting enzyme responsible for the bioluminescence of fireflies and click beetles. The enzyme catalyses the oxidation of firefly luciferin, requiring oxygen and ATP. Because of the requirement of ATP, firefly luciferases have been used extensively in biotechnology.
Light production in fireflies is due to the chemical process of bioluminescence. This occurs in specialized light-emitting organs, usually on a female firefly's lower abdomen. The enzyme luciferase acts on luciferin, in the presence of magnesium ions, ATP, and oxygen to produce light. Oxygen is supplied via an abdominal trachea or breathing tube.
Signal transduction pathways in the photocyte of the firefly have been hypothesized to play a role in decreasing the activity of the mitochondria to make oxygen available for the production of light in fireflies. Because the neurons that control the lighting mechanism of the photocytes terminate at the tracheal cells instead of the photocytes ...
A project is underway to investigate the production of “dark” oxygen further. Understanding the phenomenon better could help space scientists find life beyond Earth Scientists say they found ...
With only a few hours of oxygen left, Mal has the crew leave in the two shuttles while he remains aboard and hopes to contact a passing ship. In a series of flashbacks, Mal convinces Zoe, Jayne, Inara, Hoban Washburne, and Kaylee Frye to join his crew. In the present, Mal can hail a ship and secure the part needed to fix the engine, though he ...
Luciferase is a generic term for the class of oxidative enzymes that produce bioluminescence, and is usually distinguished from a photoprotein.The name was first used by Raphaël Dubois who invented the words luciferin and luciferase, for the substrate and enzyme, respectively. [1]
From currently studied systems, the only unifying mechanism is the role of molecular oxygen; often there is a concurrent release of carbon dioxide (CO 2). For example, the firefly luciferin/luciferase reaction requires magnesium and ATP and produces CO 2, adenosine monophosphate (AMP) and pyrophosphate (PP) as waste products.
"Out of Gas" is the eighth episode of the science fiction television series Firefly created by Joss Whedon. It differs stylistically from the rest of the series, in that it tells its story alternately in three timeframes: events in the present, events in the near-past that led to the present, and events in the past that led to the formation of Serenity's core crew.
