Histidine decarboxylase proenzyme, N-terminal (IPR016106)

Short name: Pyr-dep_his-deCO2ase_N

Overlapping entries


This entry represents a structural subdomain found at the N terminus in Histidine decarboxylase proenzyme. This subdomain has an irregular structure containing both beta-strand and alpha-helical regions. These proteins form heterohexamers [PMID: 11243783].

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.
