| protein-serine-threonine kinases | <enzyme> A group of enzymes that catalyses the phosphorylation of serine or threonine residues in proteins, with ATP or other nucleotides as phosphate donors. Registry number: EC 2.7.10 (12 Dec 1998) |
| protein-serine-threonine phosphatase | <enzyme> Consider also EC 3.1.3.16 phosphoprotein phosphatases Registry number: EC 3.1.3.- Synonym: serine phosphatase, threonine phosphatase, protein-serine phosphatase, serine-threonine phosphatase (26 Jun 1999) |
| threonine | <amino acid> The hydroxylated polar amino acid. (15 Oct 1997) |
| threonine acetaldehyde-lyase | <enzyme> Catalyses conversion of threonine to glycine and acetaldehyde; do not confuse with threonine aldolase (EC 2.1.2.1) Registry number: EC 4.1.2.5 Synonym: l-threonine acetaldehyde-lyase, d-threonine acetaldehyde-lyase, threonine aldolase (lyase) (26 Jun 1999) |
| threonine deaminase | <enzyme> A pyridoxal-phosphate protein that catalyses 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. Chemical name: L-Threonine hydro-lyase (deaminating) Registry number: EC 4.2.1.16 (12 Dec 1998) |
| threonine dehydratase | <enzyme> A pyridoxal-phosphate protein that catalyses 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. Chemical name: L-Threonine hydro-lyase (deaminating) Registry number: EC 4.2.1.16 (12 Dec 1998) |
| threonine permease | <chemical> Membrane-associated threonine permease encoded by tdcc gene of E coli Chemical name: permease, threonine Synonym: threonine-serine permease, tdcc gene product (26 Jun 1999) |
| threonine-trna ligase | <enzyme> An enzyme that activates threonine with its specific transfer RNA. Chemical name: L-Threonine:tRNA(Thr) ligase (AMP-forming) Registry number: EC 6.1.1.3 (12 Dec 1998) |
| falciparum exported serine-threonine protein kinase | <enzyme> Isolated from plasmodium falciparum; genbank u40232 Registry number: EC 2.7.10.- Synonym: fest kinase (26 Jun 1999) |
| Fas-activated serine-threonine kinase | <enzyme> Phosphorylates tia-1 during fas-mediated apoptosis; contains proline-rich sh3-binding domains; mw 60-63 kD; genbank x86779 Registry number: EC 2.7.10.- Synonym: fast kinase (26 Jun 1999) |
| (3-(arginyl)amino-4-(4-nitrophenyl)butyryl)-leucyl-prolyl-threonine | Pharmacological action: neurotransmitters Synonym: 2-afb(p-no2)-proctolin, (afb(p-no2)(2))-proctolin (26 Jun 1999) |
