Figure 3. Amine oxidase activity of the four different haplotype variants of LOXL1 toward elastin, type I collagen, or cadaverine. The
reactions without BAPN are in gray, and the reactions with BAPN are in white. The amine oxidase activity is expressed as nM
of H2O2 produced per μg of the LOXL1 variant protein. Standard deviations are indicated in each graph, and the p-values between the
reactions with and without BAPN are less than 0.05 in all cases tested.
