Unraveling Mycobacterium tuberculosis acid resistance and pH homeostasis mechanisms
Mycobacterium tuberculosis exhibits a remarkable resilience to acid stress. In this Review, we discuss some of the molecular mechanisms and metabolic pathways used by the tubercle bacilli to adapt and resist host‐mediated acid stress. Mycobacterium tuberculosis (Mtb) is a successful pathogen that has developed a variety of strategies to survive and ...

Overcharging of zinc ion in the structure of zinc finger protein is needed for DNA binding stability [PDF]
The zinc finger structure where a Zn2+ ion binds to 4 cysteine or histidine amino acids in a tetrahedral structure is very common motif of nucleic acid binding proteins. The corresponding interaction model is present in 3% of the genes of human genome.

In vitro protease cleavage and computer simulations reveal the HIV-1 capsid maturation pathway [PDF]
HIV-1 virions assemble as immature particles containing Gag polyproteins that are processed by the viral protease into individual components, resulting in the formation of mature infectious particles. There are two competing models for the process of forming the mature HIV-1 core: the disassembly and de novo reassembly model and the non-diffusional ...

Interplay of Staphylococcal and Host Proteases Promotes Skin Barrier Disruption in Netherton Syndrome. [PDF]
Netherton syndrome (NS) is a monogenic skin disease resulting from loss of function of lymphoepithelial Kazal-type-related protease inhibitor (LEKTI-1).

Venom peptides have shown promise in treating pain. Our study uses computer screening to identify a peptide that targets a sodium channel (NaV1.7) linked to chronic pain. We produced the peptide in the laboratory and refined its design, advancing the search for innovative pain therapies.

Amino acid frequency and domain features serve well for random forest based classification of thermophilic and mesophilic protein; a case study on serine proteases [PDF]
Thermostability is an important prerequisite for enzymes employed for industrial applications. Several machine learning based models have thus been formulated for protein classification based on this particular trait. These models have employed features derived from sequences, structures or both resulting in a >93% accuracy based on a 10-fold cross ...

2-D zymographic analysis of Broccoli (Brassica oleracea L. var. Italica) florets proteases: Follow up of cysteine protease isotypes in the course of post-harvest senescence. [PDF]
Zymographic analysis of Broccoli florets (Brassica oleracea L. var. Italica) revealed the presence of acidic metallo-proteases, serine proteases and cysteine proteases.

miRNA‐29 regulates epidermal and mesenchymal functions in skin repair
miRNA‐29 inhibits cell‐to‐cell and cell‐to‐matrix adhesion by silencing mRNA targets. Adhesion is controlled by complex interactions between many types of molecules coded by mRNAs. This is crucial for keeping together the layers of the skin and for regenerating the skin after wounding.

Fractional-order susceptible-infected model: definition and applications to the study of COVID-19 main protease [PDF]
We propose a model for the transmission of perturbations across the amino acids of a protein represented as an interaction network. The dynamics consists of a Susceptible-Infected (SI) model based on the Caputo fractional-order derivative. We find an upper bound to the analytical solution of this model which represents the worse-case scenario on the ...

Determination of Substrate Specificity of the Purified Novel Plant Cysteine Protease Solanain From the Latex of Vallaris solanacea [PDF]
Peptide synthesis refers to the production of peptides. Proteases are the enzymes that degrade proteins. They hold first place in the world market of enzymes, estimated at ∼US$3 billion.
