From: Evolution of mosaic operons by horizontal gene transfer and gene displacement in situ
Operon | Recipient organism and correspondent genes | Probable source | Other probable recipients | Comment |
---|---|---|---|---|
Operon acquisition | ||||
Pyruvate:ferredoxin oxidoreductase | Thermotoga maritima TM0015-TM0018 | Archaea | Aae, Hpy, Bha/Sau | Apparently, the related operon for 2-oxoisovalerate oxidoreductase (TM1758-TM1759) was also transferred from archaea |
Sulfate/molybdate transport | Bacillus halodurans BH3128-BH3130 | Gram-negative bacteria | - | No other such operons in Bacillus-Clostridium group members |
Putative effector of murein hydrolase | Pyrococcus horikoshii PH1801-PH1802 | Bacteria | Pab, Mac | Â |
Allophanate hydrolase subunits | Pyrococcus horikoshii PH0987-PH0988 | Bacteria | Pab | Â |
Paralogous operon acquisition | ||||
Dipeptide transporter | Vibrio cholerae VC0620-VC0616 | Thermotoga/Archaea | Tma | It has several another bacterial operons including VC1091-VC1095 |
Ribonucleotide reductase alpha and beta subunit | Halobacterium sp. VNG2384G VNG2383G | Bacteria | - | Additional to "archaeal:" Ribonucleotide reductase alpha subunit VNG1644G, beta subunit is apparently lost |
Aromatic amino-acid biosynthesis | Halobacterium sp. VNG0384G VNG0386G | Bacteria | - | Paralogs of this pair are VNG1646G-VNG1647G |
Xenologous operon displacement | ||||
