One-pot method for recombinant geranylgeranylated protein production

Patent published on the 2026-06-11 in WO under Ref WO2026122736 by MOZHDEHI DAVOUD [US] (Alam Md Mahbubul [us], Mozhdehi Davoud [us])

Abstract: A method for the one-pot production of geranylgeranylated proteins in Escherichia coli. E. coli is engineered to express geranylgeranyl pyrophosphate synthase, an enzyme that catalyzes production of geranylgeranyl pyrophosphate, and a target protein. By co-expressing GGS with a geranylgeranyltransferase, efficient geranylgeranylation of model protein substrates was achieved, including intrinsically disordered elastin-like polypeptides (ELPs) and the globular protein mCherry. This modification af[...]


Our summary: A one-pot method for producing geranylgeranylated proteins in E. coli was developed. The method involves co-expressing geranylgeranyl pyrophosphate synthase and geranylgeranyltransferase for efficient modification of target proteins. This approach is scalable and cost-effective, enhancing studies on lipid-modified proteins for drug delivery and tissue engineering.

Kovacs-like memory effect in strain stiffening collagen networks

Published on 2026-06-10 by Abhishek Ghadai, Maitri Mandal and Sayantan Majumdar @IOP SCIENCE

Abstract: Materials driven far from equilibrium can encode memories of past deformations through long-lived structural reorganizations. Such memory effects-reflecting parameters such as deformation direction, magnitude, and duration have been widely explored in soft amorphous solids. Here, we report a Kovacs-like memory effect manifested as a non-monotonic stress relaxation in vitro biopolymer networks formed by type-I collagen, an essential component of the mammalian extracellular matrix. Using shear rhe[...]


Our summary: The study identifies a Kovacs-like memory effect in type-I collagen networks. This effect is linked to non-monotonic stress relaxation during nonlinear strain-stiffening. The findings reveal a correlation between memory response and negative normal stresses in biopolymer networks.
