核酸酶

An enzyme that promotes the hydrolysis of urea to form ammonium carbonate.

核酸酶水解核酸的酶，如核酸内切酶和核酸外切酶

The results showed that:(1) 5'-nucleotide contents in yeast autolysate was slightly increased by adding RNase frommalted barley roots;(2) higher pH did not improve the 5'-nucleotide contents even in the presence of RNase from malted barleyroots, but at the pH 8.0, the addition of Acalase could increase the final yield, soluble protein contents and 5'-nucleotide inthe presence of RNase from malted barley roots.

酵母核酸酶的pH稳定性和温度稳定性均比麦芽根核酸酶的要差。这说明自溶法生产酵母提取物时，即使外加5'-磷酸二酯酶不能有效提高呈味核苷酸的原因并非由于外加的5'-磷酸二酯酶性质不稳定，而是另有其它原因。

We have investigated the conformational features of four short peptide fragments of Staphylococcal nuclease by homonuclear two-dimensional NMR and circular dichroism with a view to examining the early events in the folding process of SNase.

双胸蚓组织中核酸酶粗提物的制备及核酸酶的纯化以SDS-PAGE-DNA功能胶和琼脂糖凝胶电泳测活相结合作为双胸蚓组织核酸酶提取过程中核酸酶活性的监测体系。

Micrococcal nuclease hypersensitive DNA fragments were either cloned directly, or mapped onto the genome by hybridization with oligo-nucleotide probes on a 244K Agilent array-CGH chip. The array-CGH mapping was confirmed for nuclease sensitivity by PCR after MNase digestion and by Southern blot analysis.

我们利用小球菌核酸酶超敏感的去氧核醣核酸片段直接选殖或是将其作为寡核苷酸探针於安捷伦244k寡核苷酸阵列-比较基因体杂合晶片上，进行基因体定位，并利用聚合酶链索反应和南方墨点法侦测其核酸酶敏感程度，以确认结果之可靠性。
