The Internal Structure of the Velvet Worm Projectile Slime: A Small-Angle Scattering Study

Alexander Baer et al.

Summary: To understand the mechanoresponsive behavior of the bio-adhesive slime, the nanostructural organization of its components was studied using small-angle scattering with neutrons and X-rays. It was found that the majority of slime proteins exist freely in solution, while only less than 10% are contained in nanoglobules. Comparing scattering data of slime re-hydrated with light and heavy water revealed that the majority of lipids are contained in nanoglobules with homogeneous distribution. Vibrating mechanical impact without air did not lead to fiber formation, suggesting that interfacial phenomena and directional shearing are required for fiber formation.

Phosphonate production by marine microbes: Exploring new sources and potential function

Marianne Acker et al.

Summary: This study reveals that a small fraction of microbial producers in the ocean sustain the presence of phosphonates and allocate a significant portion of their phosphorus quota for phosphonate production. The phosphonates may be associated with cell-surface glycoproteins, mediating ecological interactions between the cell and its surrounding environment.

Complete Sequences of the Velvet Worm Slime Proteins Reveal that Slime Formation is Enabled by Disulfide Bonds and Intrinsically Disordered Regions

Yang Lu et al.

Summary: By combining transcriptomic and proteomic studies, this research obtained the complete primary sequences of slime proteins in velvet worms and identified key features for slime self-assembly. The study revealed that slime proteins contain cysteine residues that mediate the formation of multi-protein complexes via disulfide bonding. It also found that low complexity domains in the N-termini have a propensity for liquid-liquid phase separation. Moreover, the rigid and flexible domains of the slime proteins were mapped using solid-state nuclear magnetic resonance.

Global and seasonal variation of marine phosphonate metabolism

Scott Lockwood et al.

Summary: Marine microbial communities rely on dissolved organic phosphorus (DOP) remineralisation to meet phosphorus (P) requirements. This study extensively surveyed the genomic and metagenomic distribution of phosphonate metabolism pathways in marine bacteria and archaea, revealing the prevalence of substrate-specific catabolism and the less widespread broad-specificity catabolism. The study also found that phosphonate cycling genes were abundant in marine metagenomes, especially in the mesopelagic zone and during winter sampling.

Mussels Fabricate Porous Glues via Multiphase Liquid-Liquid Phase Separation of Condensates ARTICLE

Max Renner-Rao et al.

Summary: This study investigates the structure and formation process of mussel plaque, a bioinspired underwater glue composed of proteins, using 3D electron microscopic imaging. The study reveals that micro-and nanopores form spontaneously during the secretion of protein-filled secretory vesicles. Researchers also discovered that each vesicle contains a fluid condensate consisting of histidine and/or DOPA-rich proteins, which are likely the required ingredients for building the plaque. By rupturing vesicles under specific buffering conditions, controlled phase separation of different proteins occurs, resulting in the formation of a porous microplaque with fluid condensates within the pores. The results suggest that combining phase separation with tunable cross-linking kinetics could be effective for microfabricating hierarchically porous materials via self-assembly.
