AI Article Synopsis
- Plant cell wall glycans are essential for plant growth and are a valuable source of eco-friendly biomass.
- This study focuses on mapping the specific region that the monoclonal antibody (mAb) LM5 binds to, which is linked to linear beta-1,4 galactan.
- The research employs synthetic galactan analogues and various analytical techniques like carbohydrate microarrays and ELISA to investigate how the antibody interacts with the carbohydrates.
Article Abstract
Plant cell wall glycans are important polymers that are crucial to plant development and serve as an important source of sustainable biomass. The study of polysaccharides in the plant cell wall relies heavily on monoclonal antibodies (mAbs) for localization and visualization of glycans, using e.g. immunofluorescent microscopy. Here, we describe the detailed epitope mapping of the mAb LM5 that is shown to bind to a minimum of three sugar residues at the non-reducing end of linear beta-1,4-linked galactan. The study uses de novo synthetic analogues of galactans combined with carbohydrate microarray and competitive inhibition ELISA for analysis of antibody-carbohydrate interactions.

Biocatalysis provides access to synthetically challenging molecules and commercially and pharmaceutically relevant natural product analogs while adhering to principles of green chemistry. Cytochromes P450 (P450s) are amongst the most superlative and versatile oxidative enzymes found in nature and are desired regio- and stereoselective biocatalysts, particularly for structurally complex hydrocarbon skeletons. We used 10 genome-sequenced Streptomyces strains, selected based on their preponderance of P450s, to biotransform the bioactive diterpenoid abietic acid.

Protein mycoloylation is a newly characterized post-translational modification (PTM) specifically found in Corynebacteriales, an order of bacteria that includes numerous human pathogens. Their envelope is composed of a unique outer membrane, the so-called mycomembrane made of very-long chain fatty acids, named mycolic acids. Recently, some mycomembrane proteins including PorA have been unambiguously shown to be covalently modified with mycolic acids in the model organism Corynebacterium glutamicum by a mechanism that relies on the mycoloyltransferase MytC.

Human body cells and our daily electronic devices both communicate information within their distinct worlds by regulating the flow of electrons across specified membranes. While electronic devices depend on the flow of electrons generated by conductive materials to communicate within a digital network, biological systems use ion gradients, created in analog biochemical reactions, to trigger biological data transmission throughout multicellular systems. Electrogenetics is an emerging concept in synthetic biology in which electrons generated by digital electronic devices program customized electron-responsive biological units within living cells.

The rising demand for plant-based meat analogues presents challenges in replicating the sensory qualities of animal meat. This study investigates the impact of Pichia-derived porcine myoglobin (PMb) and bovine hemoglobin (BHb) on the flavor profile, sensory attributes, macrostructure, color, and texture of high-moisture extruded soy protein concentrate-wheat gluten. The addition of PMb and BHb significantly altered the flavor profile by decreasing aldehyde content (hexanal and nonanal), while the contents of ketones (2,3-octanedione and 3,5-octadien-2-one), pyrazines (2-ethyl-6-methylpyrazine), and furans (2-pentylfuran) were increased.

The widespread use of electronic devices has led to increased blue light exposure, highlighting the need for effective radiation blockers with blue light protection. Two synthetic 2-(2'-hydroxyphenyl)benzoxazole derivatives named azo-4'-benzoxazole and azo-5'-benzoxazole have shown an unprecedented blue light absorption capacity but had not been subjected to a safety evaluation. This study aimed to evaluate the cytotoxic, genotoxic, and mutagenic activities of these compounds.
