Chaperonins GroEL and GroES sequester and ensure the correct folding of the newly synthesized large subunit (L). 

The assembly chaperone (RbcX)2 binds the large subunit and provides positional information for proper association of large subunit dimers to form the L8–((RbcX)2)8 complex. 

The small subunit (S) associates with L8–((RbcX)2)8, triggering a conformational change in RbcL and eliciting 

the release of (RbcX)2 and formation of the catalytically mature Rubisco holoenzyme [L]8–[S]8.

Instructive interaction

It occur where the responding cell has a choice of fates and will follow one developmental pathway following induction and an alternative pathway in absence of the inductive signal.
