Alanine Racemase (Crude Enzyme)
Alanine Racemase，中文名為丙氨酸消旋酶，催化L-丙氨酸與D-丙氨酸之間相互轉(zhuǎn)化。本產(chǎn)品為大腸桿菌表達(dá)的丙氨酸消旋酶，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。
This enzyme belongs to the family of isomerases, specifically those racemases and epimerases acting on amino acids and derivatives. This enzyme participates in alanine and aspartatemetabolism and D-alanine metabolism. It employs one cofactor, pyridoxal phosphate. At least two compounds, 3-Fluoro-D-alanine and D-Cycloserine are known to inhibit this enzyme.The D-alanine produced by alanine racemase is used for peptidoglycan biosynthesis. Peptidoglycan is found in the cell walls of all bacteria, including many which are harmful to humans. The enzyme is absent in higher eukaryotes but found everywhere in prokaryotes, making alanine racemase a great target for antimicrobial drug development.Alanine racemase can be found in some invertebrates.Bacteria can have one (alr gene) or two alanine racemase genes. Bacterial species with two genes for alanine racemase have one that is continually expressed and one that is inducible, which makes it difficult to target both genes for drug studies. However, knockout studies have shown that without the alr gene being expressed, the bacteria would need an external source of D-alanine in order to survive. Therefore, the alr gene is a feasible target for antimicrobial drugs. This product with the indicated enzyme activity was briefly purified from engineered E.coli.
