Adenine and guanine are also subject to spontaneous deamination. Deamination converts adenine to hypoxanthine, which hydrogen-bonds to cytosine rather than to thymine; guanine is converted to xanthine,

which continues to pair with cytosine, although with only two hydrogen bonds.

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.

The cytosolic isozymes has two distinct function, It catalyzes the conversion of citrate to isocitrate, providing the substrate for a cytosolic isocitrate dehydrogenase that generates NADPH as reducing power for fatty acid synthesis and other anabolic processes in the cytosol. It also has a role in cellular iron homeostasis
