Identification of MPUS re-annotates approximately 430 proteins.

<p>Each node represents one of the protein sequences identified as homologous to MPUS from <i>Micrococcus luteus</i>; edges between nodes are drawn only if the similarity between a pair of sequences is better than an E-value threshold cutoff of 1e⁻⁵⁰. The network is visualized using the organic layout in Cytoscape. Nodes are colored according to assigned function in UniProtKB database; megenta: DPM1, blue: apolipoprotein N-acyltransferase Lnt, red: Ppm1, cyan: MPUS. Larger nodes are proteins that are used to generate sequence alignment. Large rectangular nodes with green borders are proteins with evidence of existence at the protein level.
