无内含子前体mRNA的加工
中文名称
通路描述
真核生物mRNA的3'端是通过转录后加工延伸的原核转录本生成的。对于几乎所有RNA，3'加工包括两个步骤：首先，mRNA在编码序列下游的一个特定磷酸二酯键处被切割。上游片段随后接收约250个腺嘌呤残基组成的多聚(A)尾，而下游片段被降解。这两个部分反应是耦合的，使得反应中间体通常无法检测。虽然3'加工可以在体外作为独立事件进行研究，但在体内，它似乎与转录、剪接和转录终止有关。
英文描述
Biofilm formation Irreversible attachment of E.coli to host and other surfaces is the prerequisite for the change of the motile to a sedentary phenotype. This in turn is followed by the production of a complex mature biofilm, resulting in increased resistance towards host defenses and antimicrobial agents. In the last stage, biofilms support the release of new motile bacteria. The biofilm matrix mainly consists of polysaccharides like cellulose and colanic acid, held together by specific adhesins like curlin and Ag43 (reviewed by Van Houdt & Michiels, 2005; Laverty et al., 2014; Rossi et al., 2017).
