Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Industry—Challenge to Pro-Environmental Manufacturing of Goods Replacing Single-Use Plastic by Indian Industry: A Study Toward Failing Ban on Single-Use Plastic Access

open access: yesIEEE Access, 2023
One important topic that raised concern among researchers and population is the threat posed by the widespread presence of single-use plastic items, which has become a part of day-to-day life. An urgent need is to build a plan by manufacturers/ investors

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Plastic Sheeting: Use and procurement in humanitarian relief [PDF]

open access: yes, 2008
Plastic sheeting (also known as plastic tarpaulin, tarp, or polythene sheet) is a sheet of strong, flexible, water resistant or waterproof material. Plastic sheeting suitable for humanitarian relief is made from polyethylene.

Is reusable beverage packaging better than single–use plastic?

open access: yesSustainable Futures
We assessed the environmental impacts of seven beverage packaging types—reusable glass bottles, reusable PET bottles, reusable PP cups, and single-use PET bottles and cups (with and without recycled content)—in the European context.

Epigenetic reprogramming of lineage switching in cancer

open access: yesFEBS Letters, EarlyView.
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...
