FIGURE 4.

Portion of the 700.3-MHz gradient-enhanced two-dimensional HSQC spectrum of S. suis serotype 1 CPS in 33 mmol/liter phosphate buffer, pD 8.0, in D₂O at 70 °C. 2 × 256 increments of 819 complex data points were acquired in the States-time-proportional phase increment mode with a digital resolution of 6.8 Hz/point in the t₂ dimension and 96.3 Hz/point in the t₁ dimension. The t₂ dimension was processed by multiplication with a π/2 shifted sine bell window function, zero filling, Fourier transform, and phase correction, and the t₁ dimension was processed by Zhu-Bax linear prediction to 512 points, multiplication with a π/2 shifted sine bell window function, Fourier transform, and phase correction. Only positive contours are shown.
