Full-Length cDNA, Prokaryotic Expression, and Antimicrobial Activity of UuHb-F-I from Urechis unicinctus

Figure 2

Multiple alignment of amino acid sequences of UuHb-F-I with other known globins. Amino acid residues that are conserved in the same sequences are shaded in black; similar amino acids of at least 60% are shaded in gray. Numbers on the right indicate the amino acid position of the different sequences. The heme-binding domains are marked with asterisk above the alignment. The species and the GenBank accession numbers are as follows: UuHb-F-I (Urechis unicinctus hemoglobin F-I), UcHb-F-I (Urechis caupo hemoglobin F-I, GI:122733), and Ct-Hp (Capitella teleta hypothetical protein, GI:443723524).
