Definition
A spliceosomal complex that contains the U12, U5 and U6atac snRNPs bound to a splicing intermediate in which the first catalytic cleavage of the 5' splice site has occurred. The precise subunit composition differs significantly from that of the catalytic step 1, or activated, spliceosome, and includes many proteins in addition to those found in the U12, U5 and U6atac snRNPs.
