Construction scheme and characterization of palmitic acid-conjugated Uox-160AzF (a) Conjugation of Uox-160AzF and the palmitic acid analog containing an azide group (azide-Pal) via SPACC using a homo-bifunctional linker (DBCO-PEG4-DBCO) (b) The reaction mixture of Uox-160AzF and azide-Pal was further incubated with DBCO-Rho for fluorescence analysis. Fluorescence (Fluorescence Panel; excitation: 302 nm, emission: 510–610 nm) and Coomassie-stained image (Coomassie Panel) of protein gel of Uox-160AzF (lane 1) and Uox-160AzF reacted with DBCO-PEG4-DBCO linker (lane 2) taken by Bio-Rad ChemiDoc™ XRS+. M indicates a lane for molecular weight standards. (c) Enzymatic activity of Uox-160Pal relative to that of Uox-WT. Error bars represent standard deviations (n = 3). Enzymatic activity of Uox-160Pal was significantly reduced when compared to Uox-WT (two-tailed student’s t-test; *Indicates p < 0.01).
