Figure 4: Peptide observation across taxa.
From: The Pacific Northwest National Laboratory library of bacterial and archaeal proteomic biodiversity
This is a multiple sequence alignment of a section of an ABC transporter (accessions and organism given), with observed peptides from the PNNL Biodiversity Library in blue. For simplicity, we displayed sequences from the Actinobacteria phylum, with Roseiflexus as an out group. The right side of the alignment shows consistent discovery in proteomics data across the phylum and in the out group. The left side of the alignment is only observed in the proteomics data for Arthrobacter sp. FB24.
