Figure 1From: The structure of pyogenecin immunity protein, a novel bacteriocin-like immunity protein from Streptococcus pyogenesStructure of 2fu2. The structure of Sp-PIP - PDB ID: 2fu2 - shown as a four helix bundle in two orthogonal views. Both N- and C-termini of proteins are labeled and the protein is colored from blue (N-terminus) to red (C-terminus).Back to article page
