PW000166 View Pathway	metabolic Threonine and 2-Oxobutanoate Degradation Homo sapiens 2-oxobutanoate, also known as 2-Ketobutyric acid, is a 2-keto acid that is commonly produced in the metabolism of amino acids such as methionine and threonine. Like other 2-keto acids, degradation of 2-oxobutanoate occurs in the mitochondrial matrix and begins with oxidative decarboxylation to its acyl coenzyme A derivative, propionyl-CoA. This reaction is mediated by a class of large, multienzyme complexes called 2-oxo acid dehydrogenase complexes. While no 2-oxo acid dehydrogenase complex is specific to 2-oxobutanoate, numerous complexes can catalyze its reaction. In this pathway the branched-chain alpha-keto acid dehydrogenase complex is depicted. All 2-oxo acid dehydrogenase complexes consist of three main components: a 2-oxo acid dehydrogenase (E1) with a thiamine pyrophosphate cofactor, a dihydrolipoamide acyltransferase (E2) with a lipoate cofactor, and a dihydrolipoamide dehydrogenase (E3) with a flavin cofactor. E1 binds the 2-oxobutanoate to the lipoate on E2, which then transfers the propionyl group to coenzyme A, producing propionyl-CoA and reducing the lipoate. E3 then transfers protons to NAD in order to restore the lipoate. Propionyl-CoA carboxylase transforms the propionyl-CoA to S-methylmalonyl-CoA, which is then converted to R-methylmalonyl-CoA via methylmalonyl-CoA epimerase. In the final step, methylmalonyl-CoA mutase acts on the R-methylmalonyl-CoA to produce succinyl-CoA.

PW122600 View Pathway	metabolic Threonine Biosynthesis Pseudomonas aeruginosa The biosynthesis of threonine starts with oxalacetic acid interacting with an L-glutamic acid through an aspartate aminotransferase resulting in a oxoglutaric acid and an L-aspartic acid. The latter compound is then phosphorylated by an ATP driven Aspartate kinase resulting in an a release of an ADP and an L-aspartyl-4-phosphate. L-aspartyl-4-phosphate then interacts with a hydrogen ion through an NADPH driven aspartate semialdehyde dehydrogenase resulting in the release of a phosphate, an NADP and a L-aspartate-semialdehyde. The latter compound interacts with a hydrogen ion through a NADPH driven aspartate kinase / homoserine dehydrogenase resulting in the release of an NADP and a L-homoserine. L-homoserine is phosphorylated through an ATP driven homoserine kinase resulting in the release of an ADP, a hydrogen ion and a O-phosphohomoserine. O-phosphohomoserine then interacts with a water molecule and threonine synthase resulting in the release of a phosphate and an L-threonine.

This compound interacts with a hydrogen ion through an NADPH-driven aspartate semialdehyde dehydrogenase resulting in the release of a phosphate, an NADP, and an L-aspartate-semialdehyde.

The latter compound then interacts with a water molecule threonine synthase resulting in the release of a phosphate and an L-threonine. L-threonine is degraded into glycine and acetaldehyde by reacting with a threonine aldolase. Acetaldehyde can then be integrated into the mitochondria or stay in the cytosol. It is then degraded into acetyl-CoA through an aldehyde dehydrogenase.

It is administered topically, it is a recombinant thrombin identical to that of the endogenous human thrombin. Thrombin alfa is a human serine protease that cleaves fibrinogen to fibrin which leads to clot formation. Once thrombin alfa has performed its function it is rapidly inactivated by circulating endogenous plasma inhibitors.
