[http://en.wikipedia.org/wiki/Isocitrate_lyase Isocitrate Lyase] (ICL) is a metabolic enzyme that converts the metabolite isocitrate into glyoxylate and succinate. ICL is a homotetramer with each monomer being composed of 14 alpha helices, 14 beta sheets, and a magnesium ion cofactor. ICL has shown clinical relevance in the disease state [http://en.wikipedia.org/wiki/Tuberculosis Tuberculosis] where it is responsible for the persistence of ''Mycobacterium tuberculosis'' during the chronic stage of infection<ref name="genes">PMID: 18054522</ref> This survival strategy mediated by ICL is characterized by a metabolic shortcut within the [http://en.wikipedia.org/wiki/Citric_acid_cycle Citric Acid Cycle].
