Glutamyl-tRNA(Gln) amidotransferase subunit A, mitochondrial; Subunit of the trimeric GatFAB AmidoTransferase(AdT) complex; involved in the formation of Q-tRNAQ; required for remodeling of ER caused by Hmg2p overexpression; similar to bacterial GatA glutamyl-tRNA amidotransferase.

Glutamine--tRNA ligase; Glutamine tRNA synthetase; monomeric class I tRNA synthetase that catalyzes the specific glutaminylation of tRNA(Gln); N-terminal domain proposed to be involved in enzyme-tRNA interactions; Belongs to the class-I aminoacyl-tRNA synthetase family.

Uncharacterized protein YDR114C; Putative protein of unknown function; deletion mutant exhibits poor growth at elevated pH and calcium.

Uncharacterized protein YNL184C; Protein of unknown function; expressed at both mRNA and protein levels.

Protein of unknown function; required for mitochondrial genome maintenance; null mutation results in a decrease in plasma membrane electron transport; Belongs to the RRG8 family.

Translation initiation factor eIF5B; GTPase that promotes Met-tRNAiMet binding to ribosomes and ribosomal subunit joining; promotes GTP-dependent maturation of 18S rRNA by Nob1p; protein abundance increases in response to DNA replication stress; homolog of bacterial IF2.

37S ribosomal protein S12, mitochondrial; Mitochondrial protein; may interact with ribosomes based on co-purification experiments; similar to E. coli and human mitochondrial S12 ribosomal proteins; Belongs to the universal ribosomal protein uS12 family.

Mitochondrial ribosomal protein of the large subunit; two mitochondrial ribosomal proteins, YmL14 and YmL24, have been assigned to the same gene.

Mitochondrial group I intron splicing factor CCM1; Mitochondrial 15S rRNA-binding protein; required for intron removal of COB and COX1 pre-mRNAs; has separable roles in stabilizing mitochondrial 15S rRNA and in maturation of the COB and COX1 mRNAs; contains pentatricopeptide repeat (PPR) motifs; mutant is respiratory deficient and has defective plasma membrane electron transport.
