enzyme

So as far as I understand in mixed inhibition I can bind to either E or ES. When I binds to E the equilibrium of the E+S --> ES reaction shifts to the left (Le Chatelier's) and Km is increased (less affinity of E for S). However, when I binds to the ES complex, E+S --> ES equilibrium shifts to...

Hey can anyone put in clear terms what the difference between a hydrolase and a phosphatase is ? And also why is GTPase (GTP --> GDP) a hydrolase and not a phosphatase Thanks!!!!
