Isocitrate DehydrogenaseIsocitrate Dehydrogenase
Overview:Overview:
Isocitrate Dehydrogenase is an enzyme that is used during the third step of the citric acid cycle. This biological reaction is an essential process that is used to create molecules that are used for cellular energy. In this step it catalyzes the oxidative decarboxylation of isocitrate meaning that CO2 is released from the isocitrate. In addition coenzyme NAD+ is converted to an NADH. This reaction results in an alpha-ketoglutarate molecule which is then moved on to the forth step of the citric acid cycle.
Structure:Structure:
Isocitrate dehydrogenase is SCOP classified as an alpha beta structure. Its secondary composition consists of mainly alpha helices and beta sheets which are arranged into three layer alpha beta alpha sandwich structures. The entire protein consists of two side by side sandwich structures that face opposite directions. This then causes the proteins two active sites to face opposite directions as well. These two groups make up the A and B subunits of isocitrate dehydrogenase. This is a placeholder text to help you get started in placing a Jmol applet on your page.
