Function category of significantly differentially abundant (DA) proteins in ΔdprA mutant and the wild type Nm. A total of 100 DA protein sequences retrieved from UniProtKB were used as query dataset input and uploaded to BlastKOALA (KEGG Orthology and Links Annotation). The taxonomic group of genome, and the KEGG genes database file search used in the analysis were Prokaryotes:Bacteria, and species_prokaryotes.pep respectively. Approximately 92% of the DA proteins were functionally annotated (a). A bubble plot comparison of differentially less- and more- abundant proteins, the bubble size is proportional to the counts proteins (b). GIP - Genetic Information Processing; CM - Carbohydrate metabolism, AaM - Amino acid metabolism, S & CP - Signalling and cellular Processes, EM - Energy metabolism, NM - Nucleotide metabolism, Ud - Unclassified, EIP - Environmental Information Processing, MCV - Metabolism of cofactors and vitamins, and BSM - Biosynthesis of other secondary metabolism
