对于这个明确CRIPSR和可能的CRISPR都不是来自于文献的研究,而是利用前人所研究的方法预测出来的,具体方法详情见文献《The CRISPRdb database and tools to display CRISPRs and to generate dictionaries of spacers and repeats》。 我们点进一个已知明确的C...
To validate the method, we compared the PLSDB plasmids database with the CRISPR spacers database, yielding host predictions for 46% of the plasmids. When compared with reported hosts, our predictions achieved 84% concordance at the family level and 99% concordance at the phylum level. More...

If the spacer database was created with taxonomic labels, a result file with the suffix _lca_per_target.tsv is also created. The first column of this file contains the phage genome file name and the remaining columns are described in the same MMseqs2 wiki entry. Additionally, each match in...

gRNA spacer sequences were cloned into sgRNA-PBS expression vectors pCR8-sgRNA-15xPBSc or pCR8-sgRNA-15xPBS9R via an oligonucleotide-annealing protocol 30. All plasmids were subjected to restriction diagnostic tests and sequenced to ensure correct cloning. Plasmids are deposited on Addgene (...
Recent exploration of CRISPR diversity in the species belonging to the MTBC using next generation sequencing data showed that the ancestor ofM. tuberculosiscarried 68 different spacers, including one DVR that was duplicated [20] (Fig.1B). Another interesting characteristic of this ancestral version ...
