Induction of 4-hydroxycinnamate decarboxylase in Klebsiella oxytoca cells exposed to substrates and non-substrate 4-hydroxycinnamate analogs.
The 4-hydroxycinnamate decarboxylase (4-HCD)-inducing activity of several substrate analogs toward Klebsiella oxytoca was investigated. Four E-cinnamate-class compounds, E-4-hydroxycinnamic acid (1), caffeic acid (2), ferulic acid (3) and E-2,4-dihydroxycinnamic acid (4), all of which were accepted as substrates, all of which were accepted as substrates of 4-HCD, enable K. oxytoca cells to indu...
متن کاملCharacteristics of a 4-hydroxycinnamate hydroxylase purified from sorghum leaves.
A membrane-associated 4-hydroxycinnamate hydroxylase (p-coumarate hydroxylase) from green leaves of Sorghum bicolor has been purified by mercaptoethanol treatment, ammonium sulfate fractionation, and chromatography on hydroxyapatite and agarose 1.5m. Ascorbate (or reduced pyridine nucleotide) is an obligatory electron donor for the hydroxylation of 4-hydroxycinnamate, but not for p-cresol. The ...
متن کاملIdentification of the 4-hydroxycinnamate decarboxylase (PAD) gene of Klebsiella oxytoca.
A 7.1-kbp DNA fragment isolated from a wild strain of Klebsiella oxytoca was sequenced, leading to the identification of 10 open-reading frames (ORFs), including a 504-bp Pad gene. The Pad gene of the Gram-negative bacterium was subsequently expressed in Escherichia coli as a chimeric Pad. The deduced amino acid (AA) sequence of the Pad gene from wild-type K. oxytoca showed approximately 50% ho...
متن کاملA Manganese(II) 4-Hydroxycinnamate Complex with the Tripod Ligand Tris(2-benzimidazolylmethyl)amine
A six-coordinate manganese (II) complex with the tripod ligand tris(2-benzimidazolylmethyl)amine (ntb), with composition [Mn(ntb) (4-hydroxycinnamate)](4-hydroxycinnamate) · (DMF)0.5 · (H2O)3, was synthesized and characterized by elemental and thermal analyses, electrical conductivity, IR, and UV/vis spectral measurements. The crystal structure of the complex has been determined by the single-c...
متن کاملEnzymic formation of p-hydroxybenzoate from p-hydroxycinnamate.
An enzyme that converts p-hydroxycinnamate into p-hydroxybenzoate was found in rat liver. It is localized in the mitochondria and requires ATP. The activity is lost when the mitochondria are stored frozen overnight. Addition of magnesium chloride, cytochrome c, GSH, coenzyme A or potassium cyanide did not have any effect on the activity. When the rats were fed with alpha-p-chlorophenoxyisobutyr...
