Role of the unstructured N-terminal region and interacting proteins on the function of Mycobacterium tuberculosis σA
A distinctive feature of the bacterial RNA polymerase is the modular organization. The core of this enzyme, comprised of a dimer of the α subunit assembles with the β, β', and ω subunit. The core RNA polymerase enzyme ... -
Structural and functional insights into hybrid AT-less megaenzyme synthase (NRPS) and DNA-MsDps2 complexes using single particle cryo-EM
Microorganisms, mainly bacteria and fungi, are the producers of structurally diverse, complex organic compounds called as secondary metabolites. These metabolites include polyketides (PKs), non-ribosomal peptides (NRPs), ... -

Structural insights into the organization and channel behavior of Pannexin isoforms
Pannexins are large-pore ion channels structurally related to Connexins and Innexins but remain as hemichannels to release cellular ATP upon activation. Pannexins comprise three isoforms, Pannexin1, 2, and 3, with diverse ... -
Structure-function and evolution of a unique uracil DNA glycosylase, UdgX, from Mycobacterium smegmatis
Mycobacterium smegmatis, a soil bacterium, faces multiple challenges in its environment, including exposure to reactive oxygen species (ROS), reactive nitrogen intermediates (RNI), radiation, and various other chemical ... -
Studies on Δ40p53 mediated regulation of specific coding and non-coding RNAs: Consequences on cellular processes
p53 is a crucial transcriptional regulator which influences almost every possible pathway that impinges on the life of a cell. As expected of such an instrumental protein, the molecular network of p53 is as diverse as it ... -
Studying the role of small GTPase Rab14 in the regulation of endosomal function
The endomembrane system and their associated membrane trafficking are fundamental features of eukaryotic cell biology. These processes are regulated by small GTP-binding proteins that acts as molecular switches to ... -
Translation in Erythroid cells
Erythrocytes are specialized cells that perform the crucial function of gas exchange in all vertebrates. Regulation of gene expression was believed to be absent in these cells due to the absence of nucleus. It was also ... -
Translation in the 3'Untranslated Region of Mammalian Transcripts
Mammalian mRNAs generally have a 5'UTR (untranslated region), a coding DNA sequence, and a 3'UTR. The 3'UTR of mRNA is generally believed to be the untranslated region of the mRNA. However, there are certain instances ... -
Understanding cholesterol homeostasis and its impact on GPCR signalling in aging
Full text embargo One year up to July 2024 Aging is defined as the time-related deterioration of physiological functions necessary for survival of organisms. Despite significant progress in the extension of human lifespan ... -
Understanding protein structural excursions using residue networks and implications on biological function
The information required for a protein structure to fold into the native conformation is encoded in its sequence. Studying protein structures help to understand their biological function. Molecular interactions between ... -
Understanding the adaptive responses of Salmonella Typhimurium during bile stress
Salmonella Typhimurium (S. Typhimurium) is an enteric pathogen that causes gastroenteritis. Although gastroenteritis is usually non-life threatening in healthy adults, it can cause fatality in children and immunocompromised ... -
Understanding the interaction mechanism of bacterial virulence factors and effector proteins with host lipid membrane using single particle cryo-electron microscopy
Pathogenic bacteria employ an array of biological macromolecules and cellular structures that help in the initiation and progression of disease in host organism. These ‘virulence factors’ can either be secreted by the ... -
Understanding the mechanisms of polarity establishment and nuclear envelope breakdown in Caenorhabditis elegans embryos
Polarity establishment is critical for the development and stem cell lineages. The one-cell stage of the Caenorhabditis elegans embryo polarizes soon after fertilization. As a result, the first division of the embryo ... -
Understanding the role of Cysteine desulfurases in Mycobacterium tuberculosis physiology and pathogenesis
The Mycobacterium tuberculosis (Mtb) persistence inside the human host relies on successful adaptation to host-induced stresses such as reactive oxygen species (ROS), reactive nitrogen species (RNS), iron starvation, low ... -
Understanding the role of DNAJC30 and ISCU in mitochondrial homeostasis
Williams-Beuren Syndrome (WBS) is a rare multisystem genomic disorder characterized by mild to moderate cognitive impairment, unique personality traits, distinctive facial features, cardiovascular problems, and infantile ... -
Urolithin-A mitigates synaptic dysfunctions associated with epilepsy through VDAC1 inhibition: A novel therapeutic approach
Urolithin-A mitigates synaptic dysfunctions associated with epilepsy through VDAC1 inhibition: A novel therapeutic approach Epilepsies are a group of neurological disorders with a prevalence of 70 million people worldwide ... -
Venomics of Medically Important yet Neglected Elapid Snakes of India and the Antivenomic Potential of Plant Extracts
India is considered the world's snakebite capital, where over 58,000 snakebite fatalities are registered annually. Most bites are primarily attributed to four snake species: the spectacled cobra (Naja naja), common krait ...
