Figure 5From: The role of gene fusions in the evolution of metabolic pathways: the histidine biosynthesis caseHis7 multialignment. A multialignment of HIS7, HisHF and a set of representative concatenated HisH and HisF sequences from E. coli, S. solfataricus, A. fulgidus and G. sulfurreducens. Yellow shading represent insertions shared only by bifunctional HIS7 and HisHF proteins. Shading of the multialignment has been made with PAM250 matrix.Back to article page
