... The transition state is stabilized by two methods: a) a decrease in entropy due to the pre-arrangement of catalytic residues in the active site. For example the catalytic triad in serine proteases (Ser, His, Asp) or the two Asp residues in HIV protease. b) By forming direct interactions between the ...
