Abstract
Purified RNase III of Escherichia coli cleaved the initial 479-nucleotide sequence of lac operon mRNA at four specific sites and also gave limited cleavage of trp operon mRNA. This action explains the inactivation of mRNA coding capacity by RNase III in vitro.
摘要
大肠杆菌纯化的核糖核酸酶III在四个特定位点切割了乳糖操纵子信使核糖核酸的初始479个核苷酸序列，并且对色氨酸操纵子信使核糖核酸也有有限的切割作用。这一作用解释了核糖核酸酶III在体外使信使核糖核酸编码能力失活的现象。
