Hen egg-white lysozyme has a molecular weight of about 14,600 and each molecule comprises 129 amino acid residues1. The activity of lysozyme in promoting the dissolution of bacterial cell walls is now known to depend upon its ability to catalyze the hydro
Myeloperoxidase, human white blood cells (MPO) 是一种过氧化物酶,通过促进活性氧 (ROS) 和活性氮 (RNS) 的生成来调节小胶质细胞及中性粒细胞的极化,并影响炎症相关信号通路,进而介导氧化应激。此外,Myeloperoxidase, human white blood cells 还具备抗菌 (antibacterial) 活性。
Phototrexate is a photoswitchable potent inhibitor of human dihydrofolate reductase (DHFR). Phototrexate is a photochromic analog of Methotrexate. Antifolate activity is switched on (cis-Phototrexate) by UVA (375 nm) light; it can be switched off (trans-Phototrexate) by blue or white light and by thermal relaxation in the dark.cis-Phototrexate (IC50 = 6 nM) significantly reduces the viability of HeLa cells compared withtrans-Phototrexate (IC50 = 34 μM).
