Correction: Increased N-Glycosylation Efficiency by Generation of an Aromatic Sequon on N135 of Antithrombin

The images for Figs. 3 and 4 are incorrectly switched. The image that appears as Fig. 3 should be Fig. 4, and the image that appears as Fig. 4 should be Fig. 3. The figure legends appear in the correct order.

Fig 3. Function of antithrombin variants.

Anti-FXa activity of antithrombin proteins secreted to the conditioned medium in presence of heparin. Results are expressed as a percentage of the activity of the S137T variant. Each bar represents the mean ± standard deviation (SD) of two independent experiments performed in duplicate. The differences between mutants were tested by paired t-test (p-value). The “*” indicated differences statistically significant with p<0.05.

Fig 4. Scheme of binding of antithrombin and heparin.

Initial rapid equilibrium, K ₁, between antithrombin, AT, and pentasaccharide, H, leads to complex, AT.H, followed by rapid conformational change via k ₂ to a high heparin affinity, highly fluorescence complex, AT*.H.

There are errors in the Van't Hoff equation under the Materials and Methods subsection titled “Determination of denaturing temperature.” Please view the complete, correct equation here:

$$\mathrm{d}\mathrm{G}=-\mathrm{R}\mathrm{T}\mathrm{}\mathrm{L}\mathrm{n}\left(\mathrm{F}\mathrm{o}\mathrm{b}\mathrm{s}-\mathrm{}\mathrm{F}{\mathrm{n}}_0\right)/\left(\mathrm{F}{\mathrm{d}}_0-\mathrm{F}\mathrm{o}\mathrm{b}\mathrm{s}\right)\mathrm{}=\mathrm{}\mathrm{d}\mathrm{H}\mathrm{m}\mathrm{}\left(1-\mathrm{T}/\mathrm{T}\mathrm{m}\right)$$
