Genome-wide core proteome analysis of Brucella melitensis Strains for Potential Drug Target Prediction.

In this study an attempt has been made through subtractive proteomic strategy to identify novel drug targets in Brucella melitensis strains. There were 2604 core proteins of 56 strains of B. melitensis, of which 545 nonhuman homologs were found to be essential for pathogen growth. Metabolic pathway analysis of these essential proteins revealed that 129 proteins are exclusively involved in 21 unique metabolic pathways in B. melitensis reference strain. Of these, 31 proteins were found to be involved in 10 metabolic pathways which are unique to the pathogen. We selected Nitrate reductase subunit-β, Urease subunit α-2, Pantoate-β-alanine ligase, Isochorismatase, 2-dehydro-3- deoxyphosphooctonate aldolase and Serine O-acetyltransferase as a drug targets in Brucella melitensis strains. Among these druggable targets, we selected only Pantoate-β-alanine ligase as high confidence target based on intensive literature curation, which is non homologous to human gut metagenome involved in Biosynthesis of secondary metabolites pathway. Pantothenate synthetase, it the best chemotherapeutic target to combat Brucellulosis. Further in vitro and in vivo validation is needed for the evaluation of lead compound against Brucella melitensis strains. PMID: 32634082 [PubMed - as supplied by publisher]
