Atomically precise metal cluster enzymes for pathological tissue regeneration

BMEMat, EarlyView.
Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.

Reactions of DOPA (3,4-dihydroxyphenylalanine) decarboxylase with DOPA [PDF]

, 1979
The study of DOPA (3,4-dihydroxyphenylalanine) decarboxylase by steady-state methods is difficult because multiple reactions occur. The reaction with DOPA was studied at enzyme concentrations between 20 and 50 micrometer by direct observation of the ...

A Mononuclear Scenario for the Copper‐Catalyzed Monooxygenation of Phenolic Substrates

Chemistry – A European Journal, EarlyView.
ABSTRACT Whereas a dinuclear pathway applies to the monooxygenation of phenols by the type 3 copper enzyme tyrosinase, a mononuclear pathway has been identified for the same reaction in corresponding small‐molecule systems. DFT calculations of five copper model complexes reveal that the latter mechanism is energetically feasible, identifying all ...

Novel Zwitterionic Polydopamine Nanofiller‐Reinforced Hybrid Membranes With Superior Antifouling Performance for Wastewater Treatment

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.

Chemical modification of pig kidney 3,4-dihydroxyphenylalanine decarboxylase with diethyl pyrocarbonate. Evidence for an essential histidyl residue

, 1985
Diethyl pyrocarbonate inhibits pig kidney holo-3,4-dihydroxyphenylalanine decarboxylase with a second-order rate constant of 1170 M-1 min-1 at pH 6.8 and 25 degrees C, showing a concomitant increase in absorbance at 242 nm due to formation of ...

Spontaneous fibril formation in eumelanin synthesised from 3,4-dihydroxyphenylalanine

, 2011
This thesis concerns synthetic melanin formation using 3,4-dihydroxyphenylalanine (DOPA), with respect to its possible fibril formation. This study aims to bridge the gap between the understanding of L-DOPA as a precursor molecule and its formation into ...
