Summary: This study presents a novel approach for preparing tunable multifunctional biomaterials through the combination of synthetic biology and material chemistry. The genetically encoded catechol moiety in a nanofiber mat promotes self-assembly and wet adhesion property of the protein, and is further utilized for the controlled release of boric acid to accelerate wound healing. The presence of 3,4-dihydroxyphenylalanine in the nanofiber mat acts as a stimulus to trigger cell proliferation, migration, and vascularization, contributing to the acceleration of wound healing. Various spectroscopic methods confirm the structural integrity, antioxidant property, and controlled release of boric acid, while microscopy techniques reveal the 3D architecture of the nanofiber mat favorable for fibroblast growth, endothelial cell attachment, and tube formation, supporting its role as a desirable wound-healing material. Animal studies demonstrate that the multifunctional biomaterial significantly improves re-epithelialization and accelerates wound closure in a murine wound healing model.

Summary: Rubisco is a key enzyme that facilitates the entry of CO2 into the biosphere, but its catalytic properties are slow and error-prone. More effective Rubisco variants have been discovered in certain algae, offering the potential to significantly improve crop productivity. However, incompatibilities in protein folding have hindered the transplantation of these variants into plants. Directed evolution is now being explored to enhance Rubisco catalysis.

Summary: Many cancers start with a small nest of transformed cells that can remain dormant. Thrombospondin-1 (TSP-1) initially promotes dormancy by suppressing angiogenesis, but over time, factors promoting angiogenesis become dominant and recruit various cells to form a complex tumor microenvironment. TSPs play a role in the proliferation, migration, and invasion of cells in the tumor microenvironment, as well as influencing the immune characteristics and phenotype of tumor-associated macrophages.

Summary: There has been increasing attention to the role of phase-separated biomolecular condensates, specifically stress granules, in neurodegenerative diseases like ALS. ALS-associated mutations in genes involved in stress granule assembly have been found, and stress granule proteins have been detected in pathological inclusions in ALS patient neurons. However, protein components of stress granules are also present in other physiological biomolecular condensates, which have not been adequately discussed in relation to ALS. This review explores the functions of TDP-43 and FUS in physiological condensates occurring in the nucleus and neurites beyond stress granules, and discusses the impact of ALS-linked mutations on their ability to phase separate and perform their functions in stress-independent biomolecular condensates.

Summary: The Calvin Benson cycle plays a crucial role in the ecological and biotechnological aspects of bacteria. Recent studies have shed light on the regulation of this cycle in bacteria, with post-transcriptional and post-translational regulation being important in phototrophic bacteria, and transcriptional regulation being prominent in chemolithoautotrophic bacteria. Understanding the regulation of the Calvin Benson cycle has implications for enhancing CO2 fixation and improving the synthesis of desired products. Non-canonical cycles may offer potential benefits for industrial applications.
