This model describes a form of threonine ammonia-lyase, a pyridoxal-phosphate dependent enzyme, with two copies of the threonine dehydratase C-terminal domain (pfam00585). Members with known function participate in isoleucine biosynthesis and are inhibited by isoleucine. Alternate name: threonine deaminase, threonine dehydratase. Forms scoring between the trusted and noise cutoff tend to branch with this subgroup of threonine ammonia-lyase phylogenetically but have only a single copy of the C-terminal domain.
