Function
function
Component of the mitochondrial ribosome (mitoribosome), a dedicated translation machinery responsible for the synthesis of mitochondrial genome-encoded proteins, including at least some of the essential transmembrane subunits of the mitochondrial respiratory chain. The mitoribosomes are attached to the mitochondrial inner membrane and translation products are cotranslationally integrated into the membrane.

Interaction
Subunit
Component of the mitochondrial small ribosomal subunit (mt-SSU). Mature N.crassa 74S mitochondrial ribosomes consist of a small (37S) and a large (54S) subunit. The 37S small subunit contains a 16S ribosomal RNA (16S mt-rRNA) and 32 different proteins. The 54S large subunit contains a 23S rRNA (23S mt-rRNA) and 42 different proteins.
