Conserved Site

Dihydroxy-acid/6-phosphogluconate dehydratase, conserved site (IPR020558)

Short name: DiOHA_6PGluconate_deHydtase_CS

Description

Two dehydratases, dihydroxy-acid dehydratase (EC:4.2.1.9) (gene ilvD or ILV3) and 6-phosphogluconate dehydratase (EC:4.2.1.12) (gene edd) have been shown to be evolutionary related [PMID: 1624451]. Dihydroxy-acid dehydratase catalyses the fourth step in the biosynthesis of isoleucine and valine, the dehydratation of 2,3-dihydroxy-isovaleic acid into alpha-ketoisovaleric acid. 6-Phosphogluconate dehydratase catalyses the first step in the Entner-Doudoroff pathway, the dehydratation of 6-phospho-D-gluconate into 6-phospho-2-dehydro-3-deoxy-D-gluconate. Another protein containing this signature is the Escherichia coli hypothetical protein yjhG. The N-terminal part of the proteins contains a cysteine that could be involved in the binding of a 2Fe-2S iron-sulphur cluster [PMID: 8299945].

This entry contains two signature patterns: the first pattern is located in the N-terminal half and contains a cysteine that could be involved in the binding of a 2Fe-2S iron-sulphur cluster; the second pattern is located in the C-terminal half.
