Hydroxyl Radical 39-55 UPF1 RNA helicase and ATPase Homo sapiens 166-170 17131291-5 2006 The results showed that UPF1 and UPF15 are powerful hydroxyl radical scavengers and their dimerisation process velocity is higher than that of glutathione. Hydroxyl Radical 52-60 UPF1 RNA helicase and ATPase Homo sapiens 24-28 16732619-6 2006 When the oxidation is caused by hydroxyl radical (OH*), the gamma-glutamate containing peptides (UPF1 and UPF6) exhibited two to four times higher antioxidative activity (k(II) = 4.428 and 2.152 x 10(3)/M.min, respectively). Hydroxyl Radical 32-48 UPF1 RNA helicase and ATPase Homo sapiens 97-101 23062287-5 2013 UPF1, a tetrapeptide GSH analogue, 4-methoxy-L-tyrosinyl-gamma-L-glutamyl-L-cysteinyl-glycine, known to possess a 50-fold higher hydroxyl radical scavenging efficiency than does GSH, normalized the intracellular GSH level in the human bronchial epithelial cells under oxidative stress caused by CSC.
