In this issue of Cell Host & Microbe, two papers by Osuna et al. describe the characterization of AcrIIA1, an anti-CRISPR protein distributed widely among Listeria phages. AcrIIA1 functions as an anti-CRISPR and as a dynamic repressor of acr loci, suggesting it may play an important role in lysogeny.

不是您典型的抗CRISPR。

在本期《细胞宿主与微生物》中，Osuna等人发表了两篇论文。描述了AcrIIA1的特征，AcrIIA1是一种在李斯特菌噬菌体中广泛分布的抗CRISPR蛋白。AcrIIA1可作为抗CRISPR和acr基因座的动态阻遏物，表明它可能在溶菌性中起重要作用。
