Figure 6. Members of other Aca families are repressors of putative anti-CRISPR promoters.

Figure 6.

Promoter regions of acrIF1 from Pseudomonas phage JBD30, and putative promoter regions of acrIF8 from Pectobacterium phage ZF40, and acrIIC3 from a N. meningitidis prophage were cloned upstream of a promoterless lacZ gene. β-galactosidase activity was measured in the absence and presence of the indicated plasmid expressed Aca proteins in E. coli. The cognate Aca for each promoter is underlined. The mean ± SEM from three biological replicates is shown. See also Figure S6.
