Induction and Enhancement of Bacteriocin Production (Review)

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Conventionally, bacteriocins are produced by microorganisms on complex substrates, released as semi‐purified preparations or crude fermentates. These bacteriocin‐containing products often exhibit unsatisfactory purity, low active‐substance content, and high production costs, limiting their commercialization and use. This review aims to analyze

GTP cyclohydrolase II structure and mechanism

GTP cyclohydrolase II converts GTP to 2,5-diamino-6-β-ribosyl-4(3N)- pyrimidinone 5′-phosphate, formate and pyrophosphate, the first step in riboflavin biosynthesis.

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

BMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Molecular mechanism for recognition of the cargo adapter Rab6 GTP by the dynein adapter BicD2

Life Science Alliance
We present a structural model for recognition of a key modulator of protein secretion, Rab6 GTP , by the dynein adapter BicD2, which provides new insights into the trafficking of secretory vesicles. Rab6 is a key modulator of protein secretion.

Uncatalyzed Guanosine Phosphorylation under Potentially Prebiotic Conditions

Chemistry – A European Journal, EarlyView.
Pyrophosphate acts as phosphorylating agent of guanosine under simple wet‐dry cycles without condensing agent and inorganic catalysts to afford cyclic guanosine monophosphate derivatives useful for oligomerization in prebiotic processes. ABSTRACT The phosphorylation of nucleosides and their subsequent polymerization are key issues in the study of the ...

Purification, Fluorescent Labeling, and Detyrosination of Mammalian Cell Tubulin for Biochemical Assays

Cytoskeleton, EarlyView.
ABSTRACT Microtubules play essential roles in numerous cellular processes. All microtubules are built from the protein tubulin, yet individual microtubules can differ spatially and temporally due to their tubulin isotype composition and post‐translational modifications (PTMs).

Expression, Purification, and Microscopy‐Based Assays for Engineered Recombinant Tyrosinated, Detyrosinated, and Δ2 Human Tubulin

Cytoskeleton, EarlyView.
ABSTRACT Microtubules are noncovalent polymers assembled from α/β tubulin dimers. Their structure, dynamics and interaction with effectors are regulated through the expression of diverse tubulin isotypes and chemically diverse posttranslational modifications, also known as the “tubulin code.” Understanding the biophysical correlates between tubulin ...

Visualizing Specific Tubulin Isotypes and Pathogenic Variants in Cellular Microtubule Arrays

Cytoskeleton, EarlyView.
ABSTRACT Eukaryotic cells depend on dynamic microtubule arrays to execute a wide range of functions vital for life. These microtubule filaments are formed through the polymerization of α/β‐tubulin proteins, which can be generated from numerous tubulin genes, or isotypes.

Microtubule Destabilizing Kinesins: A Historical Perspective and Thoughts for the Future

Cytoskeleton, EarlyView.
ABSTRACT The microtubule cytoskeleton plays critical roles in multiple cellular processes such as mitotic spindle assembly and chromosome segregation. Cells contain a number of microtubule‐associated proteins that regulate microtubule dynamics both temporally and spatially in cells. The microtubule depolymerizing kinesins include members of the Kinesin‐
