! !tocsy data (H2O) - toxtoc4.mat (2D-TOCSY,600MHZ, from GE machine) !noesy data (H2O) - tox200noef.mat (2D-NOESY)200 ms ! (Collected in April 95 Brucker trip) ! resolution of 2D NOESY ! !Note 1: number in parentheses are number of contours seen at lvl=0.02 of NOESY-HMQC ! for weak peaks and at lvl=0.1 for others ! Nilges et al. Biopolymers 29, 813-822, (1990). ! !note 2: Naming- upfield=2 vs. downfield=1 ! Two beta protons are named downfield beta proton, hb1, ! and upfield beta proton, hb2; if degenerate, then hb*. ! For CH3 protons the protons hb11,hb12,hb13 and hb21,hb22,hb23. ! If degenerate, use hb1* for the downfield and hb2* for the upfield. ! Gamma, delta, epsilon, and eta, protons were treated in a similar manner. ! !Note 2a: Naming Ile ! gamma CH3 hg2* ! gamma CH2 hg11 hg12, if they are degenerate, then use hg1* ! gamma and delta CH3 groups are distinguishable in the HCCH-TOCSY b/c ! they give very different patterns (as per Abey) ! !note 3a: Pseudo-corrections ! (a) CH3 groups add 1.0 A to the upper limit ! (b) CH2 group with degenerate protons add 1.0 A to the upper limit ! (c) degenerate CH3 groups for V, L add 1.7 A tot he upper limit ! (d) aromatics add 2.3 A to the upper limit ! ! !Conditions for 2D 200 ms NOESY !contour level = 0.075 !# of levels= 25 !level mult= 1.4 !very strong (not used ) = 1.8 0 1.0 (1.8 to 2.8 angstroms) !strong noe (<=9 contours) = 1.8 0 1.0 (1.8 to 2.8 angstroms) !medium noe (6-8 countours) = 1.8 0 1.5 (1.8 to 3.3 angstroms) !weak noe (3-5 countours) = 1.8 0 3.2 (1.8 to 5.0 angstroms) !very weak(1-2 contours) = 1.8 0 4.2 (1.8 to 6.0 angstroms) ! on advice of A.D., very weak category is as above. !very weak(not seen at lvl=0.1) = 2.5 0 3.5 (2.5 to 6.0 angstroms !residue arbitrary assignment (nh-ppm) ! !
