The complete nucleotide sequence of a 14 kb segment of A. nidulans mtDNA reveals a rather compact organization of genes transcribed from the same strand and coding for two functionally known proteins, seven unidentified polypeptides (URFs), 24 tRNAs and two rRNAs. One of the URFs is located in the intron of the L-rRNA gene and codes for a basic protein of 410 residues. The other URFs are in spacer regions and code for hydrophobic proteins. URFa is homologous to human URF4, and URFb produces a polypeptide of 48 residues resembling the human URF6L product (hydrophobic N-terminus, basic C-terminus). The ATPase subunit 6 genes from mitochondria and E. coli appear to share a common ancestor. The codon frequencies of identified genes and URFs are similar, and codons ending with G or C are rarely used. The structures of tRNAs specific for arginine, asparagine, tyrosine and histidine are deduced from gene sequences.

UI MeSH Term Description Entries
D008928 Mitochondria Semiautonomous, self-reproducing organelles that occur in the cytoplasm of all cells of most, but not all, eukaryotes. Each mitochondrion is surrounded by a double limiting membrane. The inner membrane is highly invaginated, and its projections are called cristae. Mitochondria are the sites of the reactions of oxidative phosphorylation, which result in the formation of ATP. They contain distinctive RIBOSOMES, transfer RNAs (RNA, TRANSFER); AMINO ACYL T RNA SYNTHETASES; and elongation and termination factors. Mitochondria depend upon genes within the nucleus of the cells in which they reside for many essential messenger RNAs (RNA, MESSENGER). Mitochondria are believed to have arisen from aerobic bacteria that established a symbiotic relationship with primitive protoeukaryotes.

D010957 Plasmids Extrachromosomal, usually CIRCULAR DNA molecules that are self-replicating and transferable from one organism to another. They are found in a variety of bacterial, archaeal, fungal, algal, and plant species. They are used in GENETIC ENGINEERING as CLONING VECTORS. Episomes,Episome,Plasmid
D003576 Electron Transport Complex IV A multisubunit enzyme complex containing CYTOCHROME A GROUP; CYTOCHROME A3; two copper atoms; and 13 different protein subunits. It is the terminal oxidase complex of the RESPIRATORY CHAIN and collects electrons that are transferred from the reduced CYTOCHROME C GROUP and donates them to molecular OXYGEN, which is then reduced to water. The redox reaction is simultaneously coupled to the transport of PROTONS across the inner mitochondrial membrane.
