Fig. 4. UPGMA trees of Cas proteins were constructed with Geneious Prime 2020.2.4.
Black and gray colors indicate agreements to consensus. Cas1 and Cas2 revealed a phylogenetic pattern according to CRISPR subtypes I-E, II-C, and II-A. The accession numbers of Cas1 and Cas2 proteins were given in
Table 1. (A) Phylogenetic tree and alignment of Cas1 amino acid sequences and pairwise identity is 65.9% (B) Phylogenetic tree and alignment of Cas2 amino acid sequences and pairwise identity is 59.6%.
