| tryptophanase | A pyridoxal-phosphate protein, requiring K+. The enzyme cleaves a carbon-carbon bond, releasing indole and an unstable enamine product that tautomerizes to an imine form, which undergoes a hydrolytic deamination to form pyruvate and ammonia. The latter reaction, which can occur spontaneously, can also be catalysed by EC 3.5.99.10, 2-iminobutanoate/2-iminopropanoate deaminase. Also catalyses 2,3-elimination and β-replacement reactions of some indole-substituted tryptophan analogues of L-cysteine, L-serine and other 3-substituted amino acids. Group: Enzymes. Synonyms: L-tryptophanase; L-tryptophan indole-lyase (deaminating); TNase. Enzyme Commission Number: EC 4.1.99.1. CAS No. 9024-00-4. TNase. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-4925; tryptophanase; EC 4.1.99.1; 9024-00-4; L-tryptophanase; L-tryptophan indole-lyase (deaminating); TNase. Cat No: EXWM-4925. |  |

Enzyme Commission Number: EC 4.1.99.1. CAS No. 9024-00-4. TNase. Activity: Undetermined. Appearance: Clear to translucent yellow solution. Storage: at -20 °C or lower, for at least 1 month. Source: E. coli. L-tryptophanase; L-tryptophan indole-lyase (deaminating); TNase. Pack: 100ml. Cat No: NATE-1851. | |
| Native Escherichia coli Apotryptophanase | Apotryptophanase hydrolizes tryptophan and is capable of catalyzing α,β-elimination reactions with a number of substituted amino acids, including S-methyl-, S-ethyl-and S-benzyl-L-cysteine. DTNB inactivates tryptophanase. Applications: Apotryptophanase is used for the quantitative determination of pyridoxal-phosphate. apotryptophanase, from creative enzymes, has been used to study pregnancy-associated plp deficiency and vitamin b-6 deficiency. Group: Enzymes. Synonyms: L-tryptophanase; L-tryptophan indole-lyase (deaminating); TNase; EC 4.1.99.1; 9024-00-4. Enzyme Commission Number: EC 4.1.99.1. CAS No. 9024-00-4. TNase. Activity: 75-150 units/mg solid. Storage: -20°C. Form: soluble powder. Source: Escherichia coli. L-tryptophanase; L-tryptophan indole-lyase (deaminating); TNase; EC 4.1.99.1; 9024-00-4. Cat No: NATE-0706. | |
| 4-(Dimethylamino)cinnamaldehyde | 4-(Dimethylamino)cinnamaldehyde is a reagent used for determining indole products of tryptophan decarboxylase and tryptophanase, and can also be used for quantifying proanthocyanidins in cranberry powder. Uses: Scientific research. Group: Biochemical assay reagents. CAS No. 6203-18-5. Pack Sizes: 1 g; 5 g; 10 g; 25 g. Product ID: HY-W016729. |  |
| N-Acetyl-L-tryptophan | N-Acetyl-L-Tryptophan, is a derivative of L-Tryptophan, that can be used as a competitive inhibitor to identify and characterize tryptophanases. It can also be used as an NK1 tachykinin receptor antagonist, that may help to develop a novel therapeutic intervention for the treatment of reperfusion injury in acute ischemic stroke. Synonyms: Ac-L-Trp-OH; L-Tryptophan, N-acetyl-; N-Acetyl-Trp-OH; N-Acetyltryptophan; N-Acetyl-L-tryptophan; (2S)-2-acetamido-3-(1H-indol-3-yl)propanoic acid. Grade: ≥ 99.5% (HPLC). CAS No. 1218-34-4. Molecular formula: C13H14N2O3. Mole weight: 246.30. |  |
| tryptophan 2,3-dioxygenase | A protohemoprotein. In mammals, the enzyme appears to be located only in the liver. This enzyme, together with EC 1.13.11.52, indoleamine 2,3-dioxygenase, catalyses the first and rate-limiting step in the kynurenine pathway, the major pathway of tryptophan metabolism. The enzyme is specific for tryptophan as substrate, but is far more active with L-tryptophan than with D-tryptophan. Group: Enzymes. Synonyms: tryptophan pyrrolase (ambiguous); tryptophanase; tryptophan oxygenase; tryptamine 2,3-dioxygenase; tryptophan peroxidase; indoleamine 2,3-dioxygenase (ambiguous); indolamine 2,3-dioxygenase (ambiguous); L-tryptophan pyrrolase; TDO; L-tryptophan 2,3-dioxygenase; L-tryptophan:oxygen 2,3-oxidoreductase (decyclizing). Enzyme Commission Number: EC 1.13.11.11. CAS No. 9014-51-1. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-0531; tryptophan 2,3-dioxygenase; EC 1.13.11.11; 9014-51-1; tryptophan pyrrolase (ambiguous); tryptophanase; tryptophan oxygenase; tryptamine 2,3-dioxygenase; tryptophan peroxidase; indoleamine 2,3-dioxygenase (ambiguous); indolamine 2,3-dioxygenase (ambiguous); L-tryptophan pyrrolase; TDO; L-tryptophan 2,3-dioxygenase; L-tryptophan:oxygen 2,3-oxidoreductase (decyclizing).
