HIGHLIGHTS
- 100 T Equivalent: Prepared from Arthrobacter lutes. Essential enzyme activities are β-1,3-glucanase and β-1,3-glucan laminaripentao-hydrolase.
- Convenient: Provided lyophilized along with a storage buffer for reconstitution.
- Efficient Cell Wall Digestion: Supplied storage buffer has been optimized to confer maximum levels of enzymatic activity.
DESCRIPTION
Digestion of yeast and fungal cell walls is necessary for many experimental procedures including spheroplasting, immunofluorescence, transformation, protein purification, and others. The use of lytic enzymes like Zymolyase is routinely used for digestion. The Zymolyase from Zymo Research is prepared from Arthrobacter luteus, lyophilized, and packaged with a resuspension buffer. The buffer has been optimized to confer maximal levels of enzymatic activity. The main activities of the enzyme are β-1,3 glucanase and β-1,3-glucan laminaripentao-hydrolase, which hydrolyze glucose polymers at the β-1,3-glucan linkages releasing laminaripentaose as the principal product. Optimal Zymolyase activity is at 30° - 37°C; lytic activity ceases at higher temperatures. R-Zymolyase includes 0.5 U/µl RNase A when reconstituted. Susceptible fungal genera: Asbya, Candida, Debaryomyces, Eremothecium, Endomyces, Hansenula, Hanseniaspora, Kloekera, Kluyveromyces, Lipomyces, Metschikowia, Pichia, Pullularia, Saccharomyces, Saccharomyces, Saccharomycopsis, Schizosaccahromyces, and Torulopsis.

酶组织化学酶显示方法 1．偶联偶氮色素法 此法又称偶氮色素法(couplingazo dyemethod)，是指用某种人工合成底物在酶作用下产生分解产物，分解产物与重氮盐结合，引起偶联偶氮反应，形成不溶性偶氮色素，以此对酶定位。常用的底物是萘酚系列化合物，如l―萘酚、2―萘酚、6―溴―2―萘酚、萘酚AS、萘酚AS衍生物等。由于重氮盐的种类不同，偶氮色素的颜色也不同，可显示出紫色、蓝色、红色、褐色、棕色和黑色等各种颜色。 重氮盐有不同程度的抑制酶活性作用，因此必须选择抑制作用最弱
存在于胎盘、马睾丸等微粒体部分，使△4 -3- 氧甾醇的 A 环芳构化，变成酚型酶。开始是 19 位的甲基由 19- 羟化酶进行二次羟化成为二羟化物，接着脱水形成 19- 氧代化物，然后，在 10 位与 19 位之间切断的同时失去 1 位与 2 位的氢而成为醌，烯醇化后生成酚。因此，此系统由 19- 羟化酶与 C 10 -C 19 裂解酶构成，均需要分子态氧与 NADPH 。
