Fig. 1. Alignment and phylogenetic tree of RECQ1-like helicases across species.
Panel A, The conserved helicase core domain is indicated by yellow, the RecQ C-terminal domain (RQC) in purple, and the Helicase and RNase D C-terminal domain (HRDC) in green. Panel B, The amino acid sequences of the full length proteins in Panel A were aligned and a phylogenetic tree was constructed by ClustalX2 with number of bootstrap trials at 1000. The image was generated in Treeview. Branch numbers refer to bootstrap values.
