   3.1.12.1 | expressed in Escherichia coli Posetta DE3 |
| 3.1.12.1 | gene BH0340, recombinant expression of His-tagged enzyme Cas4 in Escherichia coli |
| 3.1.12.1 | gene Pcal_0546, phylogenetic analysis and tree |
| 3.1.12.1 | gene PF1119 or cas4-1, Cas gene loci and the adaptation assay, the cas4-1 gene is located immediately adjacent to cas1 and cas2 |
| 3.1.12.1 | gene PF1793 or cas4-2, Cas gene loci and the adaptation assay, the cas4-2 gene resides in a remote genomic location |
| 3.1.12.1 | gene SSO0001, phylogenetic analysis and tree |
| 3.1.12.1 | in TTV1, the Cas4 gene has been split into two, with the N-terminal portion becoming TP1, and lost some of the catalytic amino acid residues, apparently resulting in the inactivation of the nuclease, sequence analysis and comparison of TTV1 nucleocapsid protein TP1 |
