The binding of sugar phosphates, such as ribulose-1,5-bisphosphate, to rubisco prevents carbamylation. The sugar phosphates can be removed by the enzyme rubisco activase, in a reaction that requires ATP. The primary role of rubisco activase is to accelerate the release of bound sugar phosphates, thus preparing rubisco for carbamylation

Two transesterification reactions takes place for 2 exon -1 intron configuration. First transesterification is catalysed variably either by external G or branch point while second transesterification is always caused by exon 1 -3’OH.

There are three type of Splicing signals 

Major U2-type or GU-AG introns

Minor U12-type or AU-AC introns

Splice sites are directional in nature. 5’ splice site -the left, or donor, site and the 3’ splice site - right, or acceptor, site.
