Following are certain statements regarding activated and inactivated form of Rubisco, Which one is INCORRECT?

#Unit 6. System Physiology – Plant

The naturally occurring inhibitor 2-carboxyarabinitol 1-phosphate prevent activation of Rubisco
plant rubisco active site contains His, Asp, Glu and Lys 201 , is a carbamoylated Lys 201 side chain with a bound Mg 2+ ion and is absoluetly require for its activation
The increase in both pH and concentration of Mg2+ facilitates the formation of the (E–NH 3 + – CO2 – • Mg2+) complex, which represents the catalytically active form of rubisco
The tight binding of sugar phosphates, such as ribulose 1,5-bisphosphate (RuBP), either impedes the production of the E–carbamate adduct or blocks the binding of substrates to the carbamylated enzyme
