Threonine Deaminase (Crude Enzyme)

Threonine Deaminase，中文名為蘇氨酸脫氨酶，催化蘇氨酸脫氨，生成2-酮丁酸和氨。本產(chǎn)品為大腸桿菌表達的蘇氨酸脫氨酶，并經(jīng)簡單純化獲得的可以確保達到一定酶活力的粗酶液。
由于本產(chǎn)品需新鮮制備，確認訂購后約6個工作日才可以發(fā)貨。個別情況首次制備出現(xiàn)問題，發(fā)貨時間會順延。
本產(chǎn)品可以提供十公斤、百公斤乃至噸級的粗酶液，如有需求請聯(lián)系康朗。
Threonine ammonia-lyase, also commonly referred to as threonine deaminase or threonine dehydratase, is an enzyme responsible for catalyzing the conversion of L-threonine into alpha-ketobutyrate and ammonia. Alpha-ketobutyrate can be converted into L-isoleucine, so threonine ammonia-lyase functions as a key enzyme in BCAA synthesis.It employs a pyridoxal-5’-phosphate cofactor, similar to many enzymes involved in amino acid metabolism. It is found in bacteria, yeast, and plants, though most research to date has focused on forms of the enzyme in bacteria. This enzyme was one of the first in which negative feedback inhibition by the end product of a metabolic pathway was directly observed and studied.The enzyme serves as an excellent example of the regulatory strategies used in amino acid homeostasis. This product with the indicated enzyme activity was briefly purified from engineered E.coli.

包裝清單：

保存條件：
-20℃或更低溫度保存，至少1個月有效。
注意事項：
由于本產(chǎn)品需新鮮制備，在您確認訂購后約6個工作日才能發(fā)貨。個別情況首次制備出現(xiàn)問題，發(fā)貨時間會順延。
粗酶液的每次凍融均可能會引起部分失活，所以收到酶液后請根據(jù)需要進行分裝，并置于-20℃或更低溫度保存。
隨著保存時間的延長，酶活力會有一定程度的下降，收到產(chǎn)品后應(yīng)盡快使用。
本產(chǎn)品在生產(chǎn)和保存的過程中可能會有混濁或沉淀產(chǎn)生，融化后混勻即可，不影響正常使用。
