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(dá)的蘇氨酸脫氨酶，并經(jīng)簡(jiǎn)單純化獲得的可以確保達(dá)到一定酶活力的粗酶液。
由于本產(chǎn)品需新鮮制備，確認(rèn)訂購(gòu)后約6個(gè)工作日才可以發(fā)貨。個(gè)別情況首次制備出現(xiàn)問(wèn)題，發(fā)貨時(shí)間會(huì)順延。
本產(chǎn)品可以提供十公斤、百公斤乃至噸級(jí)的粗酶液，如有需求請(qǐng)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.
