Sequence alignment of NmPin from N. maritimus with various homologues from other phyla to investigate a potential conservation of the positively charged lysine patch of NmPin. Representatives were found by BLAST search. Each group was separately aligned to NmPin (green). Lysines of the patch (K5, K7, K31, K34, K37, K47, K48, K90) are labelled in dark blue and Arg or positively charged residues which are in close proximity to the conserved position are labelled in light blue. The positively charged patch on the surface of NmPin might be conserved also in other members of the TACK phylum. (PDF 464 kb
