An information-theoretic argument for the restriction of the current biological alphabets to 4 nucleotides and 20 amino acids [PDF]

Scientific Reports
Life as we know it is based on foldable biopolymers encoded with just 4 nucleotides or 20 amino acids. Evolution of these biopolymers requires effective and fast search of both the conformational space for folding and the sequence space for evolution ...

Panorama of the Intracellular Molecular Concert Orchestrated by Actinoporins, Pore-Forming Toxins from Sea Anemones

Toxins, 2021
Actinoporins (APs) are soluble pore-forming proteins secreted by sea anemones that experience conformational changes originating in pores in the membranes that can lead to cell death. The processes involved in the binding and pore-formation of members of

Arginine substitution by alanine at the P1 position increases the selectivity of CmPI-II, a non-classical Kazal inhibitor

Biochemistry and Biophysics Reports, 2021
CmPI-II is a Kazal-type tight-binding inhibitor isolated from the Caribbean snail Cenchritis muricatus. This inhibitor has an unusual specificity in the Kazal family, as it can inhibit subtilisin A (SUBTA), elastases and trypsin. An alanine in CmPI-II P1

Genome-Wide Analysis of the COBRA-Like Gene Family Supports Gene Expansion through Whole-Genome Duplication in Soybean (Glycine max)

Plants, 2021
The COBRA-like (COBL) gene family has been associated with the regulation of cell wall expansion and cellulose deposition. COBL mutants result in reduced levels and disorganized deposition of cellulose causing defects in the cell wall and inhibiting ...

Computer-aided design of bromelain and papain covalent immobilization

Revista Colombiana de Biotecnología, 2014
Enzymes as immobilized derivatives have been widely used in Food, Agrochemical, Pharmaceutical and Biotechnological industries. Protein immobilization is probably the most used technology to improve the operational stability of these molecules. Bromelain
