Figure 4.

Multiple alignment of amino acid sequences (species code and GenBank accession numbers in parentheses) of the CPS from P. furiosus (Pyrfu; Y09829) and CK from Pseudomonas aeruginosa (Pseae; X14693), Clostridium perfringens (Clope; X97768), Halobacterium salinarium (Halsa; X80931), Synechocystis sp (Synec; D90917), and Hemophilus influenzae (Hemin; U32741). Identical residues are marked with asterisks, and conservative substitutions are marked with points. Amino acid sequence determined by Edman degradation is flanked by two triangles.
