Computational functional and structural annotation of hypothetical proteins of Neisseria Meningitidis MC58

Neisseriameningitidis is a parasitic gram-negative bacteriumbest known for its role inmeningitis and other forms of meningococcal
disease such as meningococcemia. It is important to identify possible novel drug targets and to thrive serogroup B vaccines
against the potential pathogen because one of Neisseria meningitidis’s strains, MC58, has natural transformation capacity. Because
of the emergence of new drug resistant strains, even though several generic drugs and vaccines have been developed over time,
Neisseria meningitidis infections remain a global health problem that appeals for the development of novel drugs and vaccines against
the pathogen. In the complete genome of Neisseria meningitidis strain MC58, there are 2158 coding genes out of which 681 encodes
for hypothetical proteins (HPs). With the help of various bioinformatics tools, the extensive functional analysis of these HPs was
performed. We have analyzed 681 hypothetical proteins using various functional prediction tools like CDART, Interproscan, SMART,
Interpro, CATH and pfam. Among 682 total hypothetical proteins, we successfully annotated 436 proteins present in Neisseria
meningitidis genome. It was observed that out of 436 proteins, 13 proteins are enzymes, 26 proteins are transporters, 11 are assembly
proteins, 6 proteins involve in cell division, 70 proteins are binding proteins, 15 proteins are integral membrane proteins, 6 proteins
are catalytic domains, 15 proteins are factors, 24 proteins regulators, 3 are structural proteins, 3 are ion channels, 42 are RNA proteins,
111 proteins sequences contain a domain of unknown function (DUF), remaining proteins cannot be functionally determined by
any of the tools. These analyses suggest a possible role of hypothetical proteins in the survival, development and pathogenesis of the
organism. Further we have identified 38 hypothetical proteins as virulence causing factors using VICMpred tool. Virulence causing
proteins can serve as potent drug targets for the drug discovery process. The outcomes of this comprehensive study will be useful for
better understanding of pathogenesis, drug resistance, adaptability to host, epidemic causes and drug discovery for treatment of the
disease.
