• spliceosomal A2-2 complex biosynthesis
• spliceosomal A2-2 complex formation
• spliceosomal C1 complex biosynthesis
• spliceosomal C1 complex formation
• U12-type catalytic spliceosome formation for first transesterification step
• U2-type catalytic spliceosome formation for first transesterification step

Definition

Formation of a catalytic spliceosome complex ready to perform the first splicing reaction. This occurs by an ATP-dependent conformational change of the pre-catalytic spliceosome. 0879695897
