2D Peak List in SPARKY Format

 

 

ADAPT-NMR provides 2D peak lists in SPARKY format for all the tilted planes and orthogonal planes of the following experiments:

HNCO, HN(CO)CA, HNCA, HNCB, CBCA(CO)NH, and HN(CA)CO

 

These peak lists can be uploaded to SPARKY for any manual edition. The example shown here represents a portion of the 22o plane peak list for CBCA(CO)NH experiment from the RI-Brazzein protein.

w1 and w2 columns represent the position of the peaks in the 2D plane for 1H, and the mixture of 13C/ 15N respectively. Notice that because the second dimension is a linear mixture of 15N and 13C, presentation of these values in ppm is meaningless and therefor raw data point values from the spectra are reported.

The Height column represents the intensity of the peak in 2D spectra.

The Priority is an ADAPT-NMR scale for 2D peaks based on the intensity. Priority 1 is most probably a real peak, priority 2 is less probable, and priority 3 is the least probable to be a real peak vs. noise or artifact.

Notice that 90 degree tilted planes are basically 15N-HSQC experiment.
