Fig. 7From: The Xylella fastidosa RTX operons: evidence for the evolution of protein mosaics through novel genetic exchangesThe Xf (Temecula) RTX4 operon N-terminal repeat (sequence 1) is a chimera between sequences with homology to Rhs sequences (grey shading) and the RTX4 N-terminus (orange shading). The aligned Rhs sequence is from Escherichia coli (NCBI Accession YP_001461405). Alignments are split but the N-terminal repeat sequence is continuous (dotted line)Back to article page
