タイトル
Co-complex structure of bovine trypsin with a modified Bowman-Birk inhibitor (PtA)SFTI-1(1,14), that was 1,4-disubstituted with a 1,2,3- trizol to mimic a trans amide bond
SHEET DETERMINATION METHOD: DSSP THE SHEETS PRESENTED AS "AC" IN EACH CHAIN ON SHEET RECORDS BELOW ... SHEET DETERMINATION METHOD: DSSP THE SHEETS PRESENTED AS "AC" IN EACH CHAIN ON SHEET RECORDS BELOW IS ACTUALLY AN 6-STRANDED BARREL THIS IS REPRESENTED BY A 7-STRANDED SHEET IN WHICH THE FIRST AND LAST STRANDS ARE IDENTICAL.
PRO47-PRO48 IN THE NATIVE SEQUENCE HAS BEEN CHEMICALLY MODIFIED TO PLF TO MIMIC A TRANS AMIDE BOND.

TO 10 UL PROTEIN SOL 0.5 UL DIMETHYLFORMAMID WAS ADDED PRIOR CRYSTAL SET UP. CRYSTALS WERE SOAKED WITH PTA-SFTI (ADDED IN LYOPHYLIZED FORM TO THE CRYSTALLIZATION DROP AFTER 2 WEEKS CRYSTAL GROWTH). TOTAL SOAKING TIME 8 DAYS.
