Leptospiral imelysin (LIC_10713) is secretory, immunogenic and binds to laminin, fibronectin, and collagen IV.

Leptospirosis is a widespread zoonotic disease caused by pathogenic Leptospira. Early and accurate diagnosis is the prime step in managing the disease. Secretory proteins of Leptospira remain distinguished for diagnosis due to their availability as soluble proteins in the serum and their interaction with the host immune response due to their extracellular presence.

Identification of sigma factor 54-regulated small non-coding RNAs by employing genome-wide and transcriptome-based methods in rhizobium strains.

Unlabelled: -legume symbiosis is considered as the major contributor of biological nitrogen fixation. Bacterial small non-coding RNAs are crucial regulators in several cellular adaptation processes that occur due to the changes in metabolism, physiology, or the external environment. Identifying and analysing the conditional specific/sigma factor-54 regulated sRNAs provides a better understanding of sRNA regulation/mechanism in symbiotic association.

Osteoporosis and its Association with Vitamin D Receptor, Oestrogen α Receptor, Parathyroid Receptor and Collagen Type I alpha Receptor Gene Polymorphisms with Bone Mineral Density: A Pilot Study from South Indian Postmenopausal Women of Tamil Nadu.

The involvement of many putative genetic factors makes osteoporosis a complex disease. With increasing longevity of the Indian population, it's now being realized that, as within the West, osteoporotic fractures are also a significant explanation for morbidity and mortality in postmenopausal women. Studies have suggested that the genetic component liable for bone mass could be linked to single nucleotide polymorphisms.

Novel approaches on identification of conserved miRNAs for broad-spectrum Potyvirus control measures.

Potyviridae comprises more than 200 ssRNA viruses, many of which have a broad host range and geographical distributions. Potyvirids (members of Potyviridae) infect several economically important plants such as saffron, cardamom, cucumber, pepper, potato, tomato, yam, etc. Cumulatively, potyvirids cause a substantial economic loss.

Comparative study of potyvirid NIa proteases and their cleavage sites.

Nuclear inclusion a protease (NIaPro), a major protease of potyvirids, processes its cognate viral polyprotein at distinct cleavage sites. Although Potyviridae is the largest family of the realm Riboviria, the individual NIaPro enzymes and their cleavage sites are believed to be species-specific. In the present study, the NIaPro amino acid sequences of 165 potyvirids of 10 genera and their 1154 cleavage sites were compared to understand their genus/species-specificity and functional regulation.

Novel interactions of cardamom mosaic virus VPg with cardamom histones H3 and H4.

The host genome targeting potyviral proteins is sparsely reported. Viral genome-linked protein (VPg) is a multifaceted protein known for its interactions with a suite of host proteins, guides essential viral life cycle processes such as genome replication, translation, genome packing, and antiviral defence. Besides, VPg also plays a crucial role in assisting the transport of nuclear inclusion a protease (NIa protease) into the host nucleus.

Triton X-114 Fractionated Subcellular Proteome of Leptospira interrogans Shows Selective Enrichment of Pathogenic and Outer Membrane Proteins in the Detergent Fraction.

The Triton X-114-based solubilization and temperature-dependent phase separation of proteins is used for subcellular fractionation where, aqueous, detergent, and pellet fractions represents cytoplasmic, outer membrane (OM), and inner membrane proteins, respectively. Mass spectrometry-based proteomic analysis of Triton X-114 fractions of proteomic analysis of Leptospira interrogans identified 2957 unique proteins distributed across the fractions. The results are compared with bioinformatics predictions on their subcellular localization and pathogenic nature.

Two new mutations in dnaJ suppress DNA damage hypersensitivity and capsule overproduction phenotypes of Δlon mutant of Escherichia coli by modulating the expression of clpYQ (hslUV) and rcsA genes.

Lon is a major ATP-dependent protease of E. coli involved in degradation of abnormal misfolded proteins and specific regulatory proteins. Absence of Lon in E.

Genome of a known but distinct begomovirus associated with a novel satellite molecule infecting a new host bitter gourd ().

(KY860899), (KY860898) and (KY848691) were found to be associated with leaf curl disease in (bitter gourd). The complete nucleotide sequence of showed 82% identity with (KM244719), whereas was 96% identical to (KP868764) and illustrated 81% similarity with (JQ041697). Phylogenetic and RDP analysis revealed the proximity of these begomoviruses with other monopartite begomoviruses and alphasatellites already reported from India.

The first complete genomic sequence of cardamom mosaic virus, a member of the genus Macluravirus (family Potyviridae).

The complete genome sequence of the KS isolate of cardamom mosaic virus (CdMV) was determined using transcriptome sequencing data from CdMV-infected Elettaria cardamomum as well as from overlapping cDNA clones made from RNA extracted from viral particles. The viral genome consists of 8249 nucleotides (nt) and encodes a large polyprotein of 2636 amino acids (aa). The polyprotein of CdMV shared 48.

Prediction and identification of novel sRNAs involved in Agrobacterium strains by integrated genome-wide and transcriptome-based methods.

Small RNAs (sRNAs) are a class of gene regulators in bacteria, playing a central role in their response to environmental changes. Bioinformatic prediction facilitates the identification of sRNAs expressed under different conditions. We propose a novel method of prediction of sRNAs from the genome of Agrobacterium based on a positional weight matrix of conditional sigma factors.

Hubei poty-like virus 1 is likely an interspecies recombinant of sugarcane mosaic virus and putative bean yellow mosaic virus.

Wuhan poty-like virus 1 is a possible member of the genus Macluravirus.

We have analysed the genome sequence of Wuhan poty-like virus 1 (WuPLV1), reported as an unclassified RNA virus in GenBank (Accession no: KX884573.1). Based on the polyprotein sequence identity (ranging from 55.

Proteomic approach and expression analysis revealed the differential expression of predicted leptospiral proteases capable of ECM degradation.

Leptospira, the causative agent of leptospirosis is known to have many proteases with potential to degrade extracellular matrix. However, a multipronged approach to identify, classify, characterize and elucidate their role has not been attempted. Our proteomic approach using high-resolution LC-MS/MS analysis of Triton X-114 fractions of Leptospira interrogans resulted in the identification of 104 proteases out of 130 proteases predicted by MEROPS.

Molecular modeling and in-silico engineering of Cardamom mosaic virus coat protein for the presentation of immunogenic epitopes of Leptospira LipL32.

Expression of Cardamom mosaic virus (CdMV) coat protein (CP) in E. coli forms virus-like particles. In this study, the structure of CdMV CP was predicted and used as a platform to display epitopes of the most abundant surface-associated protein, LipL32 of Leptospira at C, N, and both the termini of CdMV CP.
