" /> threonine dehydratase - CISMeF





Preferred Label : threonine dehydratase;

MeSH definition : A pyridoxal-phosphate protein that catalyzes the deamination of THREONINE to 2-ketobutyrate and AMMONIA. The role of this enzyme can be biosynthetic or biodegradative. In the former role it supplies 2-ketobutyrate required for ISOLEUCINE biosynthesis, while in the latter it is only involved in the breakdown of threonine to supply energy. This enzyme was formerly listed as EC 4.2.1.16.;

MeSH synonym : ammonia-lyase, threonine; threonine deaminase; threonine dehydrase; dehydratase, threonine; deaminase, threonine; dehydrase, threonine; threonine ammonia-lyase; threonine ammonia lyase;

MeSH CAS label : L-Threonine hydro-lyase (deaminating);

MeSH Related Number : 9024-34-4 (CAS RN);

Registry Number MeSH : EC 4.3.1.19;
