Therefore, those essential proteins were excluded having sequence similarity with human proteome or gut flora. Only 13 proteins can be considered as putative drug targets (Table 1). Toxin secretion ABC transporter, ATP-binding/permease protein. • Biological process: Involved in the biological process pf proteolysis Probable DNA-directed RNA polymerase subunit delta. • Biological process: transcription Regulatory ON-1910 protein spx. • Biological process: Transcription regulation Conserved protein domain with no predicted function. Putative uncharacterized protein with no predicted function. Preprotein translocase SecY family protein • Cellular component: Membrane Putative preprotein translocase, SecG

subunit. Probable DNA-directed RNA polymerase subunit delta. • Biological process: protein secretion Putative uncharacterized protein. Initiation-control protein yabA. • Biological process: DNA replication. Putative ABC transporter, permease protein. Ribociclib solubility dmso In total there were 26 virulent genes which were retrieved from literature and 4508 from the SMD data. No paralogs were found to any gene as gene duplication is a rare phenomenon.19, 20 and 21 All the probable virulent genes were subjected to essentiality test to which only 50 were found to be essential and were subjected to BLAST against gut flora which gave us 32 genes and with humans gave us only 9.

These 9 could be called as putative drug targets. The present study revealed new putative drug targets (genes or their products) against Streptococcus pnemoniae. This putative drug targets may help in the development of novel antibiotics or potential drug targets which could be targeted against S. pnemoniae and these targets should not be similar to the host genome (H. sapiens, E. coli) which may lead to

allergic reactions or toxic effects. The author has none to declare.

“Lower respiratory tract infections (LTRIs) are one of the leading causes of death world-wide.1 Urinary tract infections (UTIs) are the second most commonly found in women and it has been estimated that about one-third of adult women have experienced UTIs at least twice.2 A variety of bacterial pathogens are responsible for LRTIs and UTIs, but the most prominent are Escherichia coli, Enterococcus spp., Pseudomonas aeruginosa, Proteus mirabilis, Klebsiella pneumoniae, Enterobacter spp., and coagulase-negative staphylococci. 3 and 4 Resistance to antibiotics has increasingly been reported in recent years and most of the pathogens have become resistant to third-generation cephalosporins. 5 Antibiotic resistance being the first cause of failure of therapy particularly in Acinetobacter baumannii, P. aeruginosa, K.
