Histidine decarboxylase in Enterobacteriaceae revisited.
With a modification of Taylor's decarboxylation broth, histidine decarboxylase was detected in Enterobacter aerogenes, Morganella morganii, Raoultella ornithinolytica, and some strains of Citrobacter youngae and Raoultella planticola. This method provides a useful confirmatory test for identification of E. aerogenes strains.
متن کاملHistidine Decarboxylase in Hyaline Membrane
During the latter part of pregnancy, the foetal rat produces large quantities of histamine which may be concerned with the growth of the foetus (Kahlson and Rosengren, 1959). Kahlson (1960) reported increased formation of histamine by the human foetus as well: recently Davis (1961) suggested that the antagonism of such excess histamine might account for the beneficial effect of an antihistamine...
متن کاملA Rapid Histidine Decarboxylase Assay1
Histidine decarboxylase (EC 4.1.1.22) catalyzes the conversion of histidine to histamine. Because current assays for enzyme activity are time consuming and require additional enzymes or large amounts of tissue, a rapid radioisotopic assay was devised. Using commercially available radioactive histidine (without additional purification), the enzyme mediates the formation of histamine. The product...
متن کاملSpectroscopic analysis of recombinant rat histidine decarboxylase.
Mammalian histidine decarboxylases have not been characterized well owing to their low amounts in tissues and instability. We describe here the first spectroscopic characterization of a mammalian histidine decarboxylase, i.e. a recombinant version of the rat enzyme purified from transformed Escherichia coli cultures, with similar kinetic constants to those reported for mammalian histidine decar...
متن کاملCrystallization and Subunit Structure of Histidine Decarboxylase
Histidine decarboxylase from Lactobacillus 30u has been crystallized in a variety of forms which together indicate a revised subunit structure for the native particle. Octahedral crystals of the wild type enzyme obtained at room temperature from ammonium sulfate solutions in microdiffusion cells belong to tetragonal space group 14122 with a = b = 222 A and c = 107.5 A. Trigonal and hexagonal pl...
