Precision Chemistry for Protein Lysine Modification

open access: yesChemistry – A European Journal, EarlyView.
Selective modification of lysine residues is challenging due to their similar intrinsic reactivity. Inspired by enzymatic recognition, ligand‐guided electrophiles enable site‐selective labeling and functionalization, while ligand‐guided catalyses achieve regioselective installation of bio‐relevant post‐translational modifications.

How 1st‐Tier Suppliers Respond to Green Public Procurement Policies: An Empirical Analysis

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This article analyses how 1st‐tier suppliers to public organisations respond operationally to Green Public Procurement (GPP) policies. Through a multiple case study of 12 Italian firms operating in different sectors, we develop a classification of suppliers' responses, identifying two interrelated macro‐types: internal operations realignment ...
