>TIGR02079 THD1 threonine dehydratase; InterPro: IPR011820 This entry represents threonine dehydratase, the first step in the pathway converting threonine into isoleucine. At least two other clades of biosynthetic threonine dehydratases are described by IPR005787 from INTERPRO and IPR005789 from INTERPRO. The sequences described by this entry are exclusively found in species containing the rest of the isoleucine pathway and which are generally lacking in members of the other two clades of threonine dehydratases. The sequences associated with this entry are often cluster with other elements of the isoleucine pathway.; GO: 0004794 L-threonine ammonia-lyase activity, 0030170 pyridoxal phosphate binding, 0009097 isoleucine biosynthetic process.
