Protospacer adjacent motif - Wikipedia
WEBA protospacer adjacent motif (PAM) is a 2–6-base pair DNA sequence immediately following the DNA sequence targeted by the Cas9 nuclease in the CRISPR bacterial adaptive immune system. [1] The PAM is a component of the invading virus or plasmid, but is not found in the bacterial host genome and hence is …

WEBCRISPR-Cas基因编辑系统产生切割的3个必要条件：Cas蛋白、sgRNA和PAM，Cas蛋白是发挥识别、切割的功能蛋白，sgRNA是Cas蛋白的“导航”，而PAM是CRISPR-Cas系统区分“自我”和“入侵者”的标记，相关的结构和生化分析已经揭示了PAM参与Cas-sgRNA与靶标之间的识别机制 [1]。.

WEBpam序列非常关键，能够起到识别自身和外来的序列。 如果PAM发生单一突变（原单词是single mutation，应该可以理解为点突变），那么就能够让噬菌体入侵宿主。
PAM（protospacer adjacent motif）_百度百科
WEBThe CRISPR targeting specificity is determined both by base pairing between the RNA chimera and the target DNA and by the binding between the Cas9 protein and a short DNA motif commonly found at the 3' end of the target DNA, called the …
What is the PAM sequence for CRISPR and where is it?
WEBCRISPR-Cas9 mechanisms recognize DNA targets that are complementary to a short CRISPR RNA (crRNA) sequence. The part of the crRNA sequence that is complementary to the target sequence is known as a spacer. In order for Cas9 to function, it also requires a specific protospacer adjacent motif (PAM) that varies depending on the bacterial species ...
Deciphering, Communicating, and Engineering the CRISPR PAM
WEBJan 20, 2017 · In this review, we discuss the properties of the CRISPR PAM and the emerging tools for determining, visualizing, and engineering PAM recognition. We also propose a standard means of orienting the PAM to simplify how its location and sequence are communicated.

Deciphering, communicating, and engineering the CRISPR PAM
WEBJan 1, 2017 · While the Cas effector proteins are remarkably diverse, they commonly rely on protospacer-adjacent motifs (PAMs) as the first step in target recognition. PAM sequences are known to vary considerably between systems and have proven to be difficult to predict, spurring the need for new tools to rapidly …
