Autoimmune diseases emerge due to several reasons, of which molecular mimicry i. e., similarity between the host's and pathogen's interacting peptides is an important reason. In the present study we have reported a database of only experimentally verified peptide sequences, which exhibit molecular mimicry. The database is named as miPepBase (Mimicry Peptide Database) and contains comprehensive information about mimicry proteins and peptides of both host (and model organism) and pathogen. It also provides information about physicochemical properties of protein and mimicry peptides, which might be helpful in predicting the nature of protein and optimization of protein expression. The miPepBase can be searched using a keyword or, by autoimmune disease(s) or by a combination of host and pathogen taxonomic group or their name. To facilitate the search of proteins and/or epitope in miPepBase, which is similar to the user's interest, BLAST search tool is also incorporated.

TPWshiny: an interactive R/Shiny app to explore cell line transcriptional responses to anti-cancer drugs

Peter Zhang, Alida Palmisano, Ravindra Kumar, Ming-Chung Li, James H. Doroshow, Yingdong Zhao

Summary: The NCI TPW is a compilation of transcriptional responses to anti-cancer agents in the NCI-60 cancer cell lines, with data accessible through a web interface. TPWshiny is a standalone R application developed to provide an intuitive and comprehensive graphical interface for interactive data exploration, allowing researchers to understand how tumor cell lines respond to therapeutic agents.

Proteomics and Computational Analysis of Cytosolic Proteome of a Thermoacidophilic Euryarchaeon, Picrophilus torridus

Neelja Singhal, Anjali Garg, Nirpendra Singh, Manish Kumar, Manisha Goel

Summary: Through gel-free LC-MS/MS, 408 cytosolic proteins of P. torridus were identified, with most being multifunctional and involved in microbial metabolism activities. In comparison with gel-based LC-MS analysis, gel-free method proved to be better in identifying a greater number of proteins, including those with higher/lower molecular weights.

Heterologous expression of novel SUMO proteases from Schizosaccharomyces pombe in E. coli: Catalytic domain identification and optimization of product yields

Shilpa Mohanty, Govinda Rao Dabburu, Manish Kumar, Yogender Pal Khasa, Yogender Pal Babbal

Summary: This study identified and characterized two novel SUMO proteases, SpUlp1 and SpUlp2, from Schizosaccharomyces pombe. The catalytic domains of these proteases were able to efficiently cleave the SUMO fusion tag from proteins, making them potential candidates for large scale protein production.

Investigating the disordered regions (MoRFs, SLiMs and LCRs) and functions of mimicry proteins/peptides in silico

Anjali Garg, Govinda Rao Dabburu, Neelja Singhal, Manish Kumar

Summary: Microbial mimicry of host proteins/peptides can lead to autoimmune diseases. This study revealed that many bacterial and viral host mimicry proteins have structural disorder, but only a few overlap with host's intrinsically disordered protein regions. Most pathogens mimic host proteins involved in ion binding and signaling pathways.

Insights into the human gut virome by sampling a population from the Indian subcontinent

Kanchan Bhardwaj, Anjali Garg, Abhay Deep Pandey, Himani Sharma, Manish Kumar, Sudhanshu Vrati

Summary: This study investigated the gut DNA-virome of an unexplored ethnic population in Northern India and found that most of the identified virome belongs to bacteriophages, with a smaller fraction consisting of viruses that infect animals, archaea, protists, multiple domains or plants. The study also discovered a previously undetected virus family in the human gut. Additionally, the research revealed that the dominant lifestyle of gut phages in this population is lysogenic, which contradicts some earlier studies.

Designing dual inhibitors against potential drug targets of Plasmodium falciparum-M17 Leucyl Aminopeptidase and Plasmepsins

Govinda Rao Dabburu, Aakriti Jain, Naidu Subbarao, Manish Kumar

Summary: Malaria is a major global concern, particularly in Africa. The resistance to current antimalarial drugs is a growing problem. In this study, potential dual inhibitors of two important enzymes involved in the haemoglobin degradation pathway of Plasmodium falciparum were identified using in-silico molecular docking and simulation techniques. These novel dual inhibitors may have better efficacy than existing antimalarial drugs.

Protein expression profiling, in silico classification and pathway analysis of cariogenic bacteria Streptococcus mutans under bacitracin stress conditions

Sahar Zaidi, Manisha Aswal, Manish Kumar, Faraz Rashid, Asad U. Khan

Summary: This study aimed to explore the general stress response of S. mutans at the proteome level under cell wall stress. Through high-throughput proteomics analysis, 41 significantly overexpressed proteins and 30 significantly underexpressed proteins were identified. The upregulated proteins mainly involved sortases and proteins in the EPS biosynthesis pathway, while the downregulated proteins were primarily related to glycolysis. Sortase family of proteins are potential targets for inhibiting multiple virulence pathways simultaneously.

β-LacFamPred: An online tool for prediction and classification of β-lactamase class, subclass, and family

Deeksha Pandey, Neelja Singhal, Manish Kumar

Summary: Beta-lactams, a widely used class of antimicrobial agents, have led to the extensive spread of beta-lactamase enzymes. To counteract this effect, newer generations of beta-lactams have been developed, resulting in a highly diverse family of beta-lactamases. Traditional methods for determining the hydrolytic profile and classification of beta-lactamases are time-consuming and resource-intensive. Therefore, a machine-learning-based in silico method called beta-LacFamPred was developed for the prediction and annotation of beta-lactamases. This method showed high accuracy and outperformed other prediction tools in benchmarking tests.

ProSeqAProDB: Prosequence Assisted Protein Database

Nikita Ray, Rahul Kumar Vishwakarma, Aakriti Jain, Manish Kumar, Manisha Goel

Summary: In the early 1990s, it was discovered that certain proteins relied on additional polypeptide regions, known as prosequences/prodomains, for proper folding. While numerous examples of such proteins have been documented in literature, there has been no study investigating their evolutionary differences and similarities. The ProSeqA-ProDb database was created to comprehensively study these proteins and their prosequences. It contains a curated dataset of 2140 prosequence assisted proteins from various organisms, which will contribute to a better understanding of protein folding processes.

Aakriti Jain, Neelja Singhal, Manish Kumar

Summary: This study describes a database of all the mutations responsible for antifungal resistance, named as antifungal resistance database (AFRbase), which provides better information and visualization options compared to existing databases of antifungal resistance. AFRbase is an open access database that can be useful for genotypic susceptibility testing of fungi and studying the course of evolution of antifungal resistance. The current version of AFRbase contains 3691 unique mutations in 29 proteins of 32 fungal species along with information on the drugs causing resistance.

Public health implications of plasmid-mediated quinolone and aminoglycoside resistance genes in Escherichia coli inhabiting a major anthropogenic river of India

Nambram Somendro Singh, Neelja Singhal, Manish Kumar, Jugsharan Singh Virdi

Summary: This study investigates the presence of antimicrobial resistance genes in Escherichia coli isolated from a major river in northern India. The results show that most strains are susceptible to fluoroquinolones and some aminoglycosides, but a significant portion exhibit resistance to streptomycin, kanamycin, and gentamicin. Plasmid-mediated quinolone resistance (PMQR) genes and aminoglycoside resistance genes are identified, implying their potential transferability through plasmids.
