You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe peptidoglycan-associated lipoprotein (Pal) from Escherichia coli is part of the Tol--Pal multiprotein complex used by group A colicins to penetrate and kill cells. Pal homologues are found in many Gram-negative bacteria and the Tol--Pal system is thought to play a role in bacterial envelope integrity. The Pal protein comprises 152 amino acids. Crystals of the C-terminal 109-amino-acid fragment of the Pal protein have been produced. The crystals belong to the tetragonal space group I4(1), with unit-cell parameters a = b = 89.3, c = 67.2 A. There are two molecules in the asymmetric unit. Frozen crystals diffract to at least 2.8 A resolution using synchrotron radiation. Selenomethionine-substituted truncated Pal protein is currently being produced in order to use multiwavelength anomalous dispersion (MAD) for phasing.
