Notes

[back to top]


HPPK active center is formed once both substrates, ATP and HP, are bound and this assembly results in confirmational changes primarily in catalytic loops 1-3; catalytic loop 3 moves in the opposite direction upon binding of the nucleotide. Catalytic loop 3 is involved in ternary complex stabilization and is necessary for catalysis.[4]
