Abstract
Triclosan (TCS), a broad-spectrum antibacterial agent, exhibits a high exposure in the environment. However, the residual TCS in the environment poses a potential risk to human health. In this study, spectroscopic methods, molecular docking and animal experiment were conducted to completely understand the interaction between trypsin and TCS. The formation of the TCS-trypsin complex was spontaneously achieved through hydrogen bonds and Van der Waals forces with a binding constant (Ka) between 103 and 104 L mol-1. In addition, the trypsin activity in fish intestine was inhibited by TCS exposure, revealing the potentially negative effects of TCS on metabolism. The results might be explained by changes in the conformation of the trypsin, inducing the content of unordered coil increasing significantly (from 36.2% to over 80%). This work provides useful information for assessing the toxicity of TCS at the molecular level.

Abstract
Natural polyphenols showing a variety of beneficial effects will interact with multiple proteases after administration. The interactions of oxyresveratrol and piceatannol with trypsin and lysozyme were investigated using fluorescence spectroscopy, UV-vis absorption spectroscopy, circular dichroism spectroscopy, differential scanning calorimetry and molecular docking. Fluorescence quenching results and UV-vis absorption difference spectra revealed that the quenching process was a static mode initiated by ground-state complex formation. The different binding ability of oxyresveratrol and piceatannol with trypsin and lysozyme was discussed based on their different molecular structures. Moreover, the major driving force for the binding process was elucidated as hydrogen bonding and van der Waals forces by the negative enthalpy and entropy changes. Synchronous fluorescence, three-dimensional fluorescence and circular dichroism spectral analysis suggested that the binding of oxyresveratrol and piceatannol to trypsin and lysozyme induced some microenvironmental and conformational changes of the two enzymes. The thermal stability of the enzymes in the presence of polyphenols was studied based on the change in melting temperature by differential scanning calorimetry. The above experimental results were validated by the protein-ligand docking studies which showed the location of the two ligands in the enzymes and the surrounding amino acid residues. Furthermore, enzyme activity assays indicated that the enzymatic activity of trypsin and lysozyme was inhibited by oxyresveratrol and piceatannol. The effect of trypsin and lysozyme on the antioxidant activity and stability of oxyresveratrol and piceatannol was also investigated. In conclusion, the comparative study on the interaction of oxyresveratrol and piceatannol with trypsin and lysozyme showed that the positions of hydroxyl groups of the polyphenols had an important influence on their interaction with enzymes and their antioxidant activity and stability as well as the enzyme activities. The obtained results are expected to provide a theoretical basis for the application of polyphenols in functional foods and pharmaceuticals.

Abstract
l-Methionine (l-Met) is one of the necessary amino acids that play unparalleled roles, influencing both the protein structure and metabolism. Understanding the interactions between proteins and small molecules can be realized by various perspectives, and this is significant for the progression of basic sciences and drug development. In this study, the variations in the stability, function, and structure of α-Chymotrypsin (α-Chy) in the presence of l-Met were investigated using spectroscopic and computational approaches. The results of the UV-vis absorption demonstrated that α-Chy had a maximum peak at 280 nm due to the Trp residue. Hyperchromism shift was seen in the presence of l-Met. Ground state system was formed in the presence of l-Met, as confirmed by the fluorescence studies. Fluorescence variations also revealed static quenching. The CD spectra also represented the alteration of the enzyme with an increase in the α-helix and a decrease in the β-sheet. The activity of α-Chy was incremented in the presence of l-Met. Therefore, l-Met served as an activator. Molecular docking results also indicated a negative amount for the Gibbs free energy of the binding of l-Met to the enzyme. α-Chy became more stable in the presence of l-Met, based on the molecular dynamics simulation.
