HDC

Functionⁱ

Catalyzes the biosynthesis of histamine from histidine.By similarity

Catalytic activityⁱ

L-histidine = histamine + CO₂.

Cofactorⁱ

Pathwayⁱ: histamine biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes histamine from L-histidine.
Proteins known to be involved in this subpathway in this organism are:

Histidine decarboxylase (HDC)

This subpathway is part of the pathway histamine biosynthesis, which is itself part of Amine and polyamine biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes histamine from L-histidine, the pathway histamine biosynthesis and in Amine and polyamine biosynthesis.
