Type: | Domain | Name: | Pyruvoyl-dependent histidine/arginine decarboxylase, 3-layer sandwich domain |
Description: | This entry represents a structural subdomain found in pyruvoyl-dependent histidine decarboxylase () and arginine decarboxylase (). This subdomain consists of a 3-layer beta-beta-alpha sandwich. These proteins form heterohexamers [, ].Histidine decarboxylase catalyses the formation of histamine from histidine. It requires a pyruvoyl group for its activity. Cleavage of the proenzyme PI chain yields two subunits, alpha and beta, which arrange as a hexamer (alpha beta) 6 by nonhydrolytic self-catalysis.Arginine decarboxylase catalyses the interconversion of arginine and agmatine plus carbon dioxide. It requires a pyruvoyl group for its activity. | Short Name: | Pyr-dep_his/arg-deCO2ase_sand |
