アプリケーション
Apotryptophanase is used for the quantitative determination of pyridoxal-phosphate. Apotryptophanase, from Sigma, has been used to study pregnancy-associated PLP deficiency and vitamin B-6 deficiency .
生物化学的／生理学的作用
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 .
単位の定義
1ユニットは、0.04 mMピリドキサール-5'-リン酸存在下で、pH 8.3、37°C、10分間で、1 μgのインドールをL-トリプトファンから遊離させる酵素量です。

Expression of the Escherichia coli tryptophanase operon depends on ribosome stalling during translation of the upstream TnaC leader peptide, a process for which interactions between the TnaC nascent chain and the ribosomal exit tunnel are critical. We determined a 5.8

The kinetic and solvent deuterium isotope effects in the 4- and 5-positions of the indole ring on the enzymatic decomposition of l-tryptophan catalysed by the enzyme TPase (EC. 4.1.99.1) were determined. The isotope effects were investigated by the non-competitive method

The highly repetitive nature of the Trichomonas vaginalis genome and massive expansion of various gene families has caused difficulties in genome assembly and has hampered genome mapping. Here, we adapted fluorescence in situ hybridization (FISH) for T. vaginalis, which is

The l-tryptophan degradation product indole is a purported extracellular signaling molecule that influences biofilm formation in various bacteria. Here we analyzed the mechanisms of indole production in Fusobacterium nucleatum and the effects of tryptophan and indole on F. nucleatum planktonic

Here we describe results from a proteomic study of protein-nanoparticle interactions to further the understanding of the ecotoxicological impact of silver nanoparticles (AgNPs) in the environment. We identified a number of proteins from Escherichia coli that bind specifically to bare
