Why is serine 195 the only serine residue in chymotrypsin that
rapidly reacts with the active site poison DIPF?
A. DIPF reacts with serine 195 in the zymogen form,
chymotrypsinogen
B. Chymotrypsin has only one serine residue
C. DIPF targets the reactive environment of chymotrypsin’s
active site
D. DIPF actually reacts rapidly with many serines, but only the
reaction with serine 195 cannot be reversed
E. Serine 195 is distant from the active site
Why is serine 195 the only serine residue in chymotrypsin that rapidly reacts with the active site poison DIPF? A. DIPF
