Cyclic Comonomers for the Synthesis of Carboxylic Acid and Amine Functionalized Poly(l-Lactic Acid)
Molecules, 2015 Degradable aliphatic polyesters such as poly(lactic acid) are widely used in biomedical applications, however, they lack functional moieties along the polymer backbone that are amenable for functionalization reactions or could be the basis for ...

Reconstructing enzyme evolution by protein engineering
FEBS 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 ...

Lysyl oxidase (LOX)‐mediated remodeling of the extracellular matrix
FEBS Letters, EarlyView.The lysyl oxidase (LOX) family of enzymes drives extracellular matrix remodeling by oxidizing collagen, elastin, and fibronectin, promoting covalent cross‐link formation. This activity regulates tissue architecture and mechanical properties, while its dysregulation contributes to fibrosis, cardiovascular disease, glaucoma, connective tissue disorders ...
