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.

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.
