Fig. 3. — Comparison of amino acids sequences of the excisionases (Xis) present in the Pf prophages. XisF4 (present in 100%, 71%, and 15% of Pf-tRNA-Gly, Pf-tmRNA, and Pf-tRNA-Sec prophages, respectively), XisF5 (present in 100%, 85%, and 29% of Pf-tRNA-DR, Pf-tRNA-Sec, and Pf-tmRNA prophages, respectively) and Xis-Met (present in 100% of Pf-tRNA-Met prophages) are represented by the following protein sequences: WP_019372529.1, WP_022581007.1, and WP_025324668.1, respectively. Amino acids characteristic for COG2452 (COG2452), excise (TIGR01764), and HTH_17 (pfam12728) conserved domains are labeled by red, blue, and magenta colors, respectively; whereas green and orange colors indicate amino acids shared by all three domains or only the excise and HTH_17 ones.
