[[http://www.uniprot.org/uniprot/MBI3_YEAST MBI3_YEAST]] Mitochondrial mRNA maturase required for splicing of intron 3 of the cytochrome b (COB) gene, containing its own coding sequence. In vivo splicing requires the formation of a ribonucleoprotein complex together with the imported mitochondrial RNA-splicing protein MRS1. The complex seems to stimulate the intrinsic ribozyme activity of intron bI3 through binding to and stabilizing specific secondary and tertiary structure elements in the RNA.<ref>PMID:11773622</ref> <ref>PMID:12924947</ref>
