Multiple sequence alignments (MSAs) of the peptidoglycan-binding site of lysins in . (a) MSA of the peptidoglycan-binding site of Muramidase family lysins grouped by the presence or absence of an N-terminal CWBD. The residue coordinates indicated at the top are those of Pae87. (b, c) Residue-conservation metrics for the residues putatively involved in contacts with peptidoglycan at the peptidoglycan-binding site according to the Pae87 3D model. The relative BLOSUM62 score is shown in (b) and the relative frequency of the Pae87 residue across the MSAs in each respective position is shown in (c). (d) SSN of the 33 sequences of the MSAs distinguished by the presence or absence of a CWBD. Percentages are average identities for each group. The entries AKU43570.1 and YP_009595839.1 were reclassified as CWBD-bearing lysins since they contained an unidentified N-terminal end that could probably be an as yet undescribed CWBD. |
