| Fmoc-TOAC-OH | Fmoc-TOAC-OH is a useful tool for the incorporation of the ESR spin-label TOAC into peptide sequences by Fmoc SPPS. Incorporation of this derivative and the following residue is best achieved using HATU activation. TFA/water/TIS should be used for cleavage of TOAC-containing peptides. The use of EDT should be avoided as it can cause permanent reduction of the nitroxide radical. Following cleavage, the TOAC peptide should be treated with aqueous ammonia in air to regenerate the nitroxide from the hydroxylamine that is generated by the TFA treatment. Uses: Peptide synthesis. Additional or Alternative Names: Fmoc-TOAC-OH, 2,2,6,6-Tetramethylpiperidine-N-oxyl-4-(9-fluorenylmethyloxycarbonyl-amino)-4-carboxylic acid. Product Category: Amino Acids. CAS No. 93372-25-9.

| Native Bacillus subtilis L-Alanine Dehydrogenase | L-Alanine dehydrogenase is an A-stereospecific dehydrogenase that catalyzes the reversible deamination of L-alanine to pyruvate and ammonium. It is important for the geneRation of pyruvate during sporulation. L-Alanine dehydrogenase from Bacillus subtilis has a predominately ordered kinetic mechanism in which NAD binds before L-alanine. Subsequently, ammonia, pyruvate, and NADH are released in that specific order. Optimal pH for the amination reaction is 8.8-9.0, whereas it is 10-10.5 for the deamination reaction. The enzyme is inactivated by divalent metal ions and p-chloromercuribenzoate, mercuric ion being most effective. The inactivation may be reversed by L-or D-...genase. Enzyme Commission Number: EC 1.4.1.1. CAS No. 9029-6-5. AlaDH. Activity: Type I, ~30 units/mg protein (Lowry); Type II, > 20 units/mg protein (Lowry). Storage: -20°C.

| Native Bovine L-Glutamic Dehydrogenase | L-glutamic dehydrogenase catalyzes the conversion of glutamate to α-ketoglutarate. Mammalian forms of this enzyme, including this bovine form, can use either NADP (H) or NAD (H) as coenzymes. L-glutamic dehydrogenase plays a unique role in mammalian metabolism. The reverse reaction catalyzed by this enzyme is the only pathway by which ammonia can become bound to the α-carbon atom of an α-carboxylic acid and thus, is the only source of de novo amino acid synthesis in mammalian species.
