| Type: | Domain | Name: | Dimeric alpha-beta barrel |
| Description: | Dimeric alpha-beta barrel domains exhibit an alpha+beta sandwich fold with an antiparallel beta sheet that forms a closed barrel. These domains dimerise through the beta-sheet, and in some cases these dimers may assemble into higher oligomers. Domains with this structure are found in proteins from several different families, including bacterial actinorhodin biosynthesis monooxygenase (ActVa-Orf6), which catalyses the oxidation of an aromatic intermediate of the actinorhodin biosynthetic pathway []; bacterial muconalactone isomerase, a decamer composed of five dimers []; and the C-terminal domain of archaeal LprA, a member of the Lrp/AqsnC family of transcription regulators []. | Short Name: | Dimeric_a/b-barrel |
