Histidine decarboxylase-mediated histamine synthesis in glomeruli from rat kidneys
JI Heald
and
TM Hollis
Enzymatic histamine synthesis by renal glomeruli of the rat has been examined. Assays of the partially purified enzyme demonstrated a pH optimum of 6.2, a Michaelis-Menten constant of 2.4 X 10(-4) histidine, and lack of potentiation by benzene. These data thus indicate that renal glomeruli contain the histidine-specific histidine decarboxylase.
