Quercetin Inhibition of Specific Histidine Decarboxylase

open access: yesExperimental Biology and Medicine, 1964
SummaryQuercetin by an isotopic method has been shown to be an effective inhibitor of non-specific and specific (induced) histi-dine decarboxylase both in vivo and in vitro.

Screening for biogenic amines production by lactobacillus species and development of functional food, tea curd [PDF]

open access: yes, 2013
Biogenic amines (BA) are substances with one or more than one amine groups.BA is organic, basic nitrogenous compounds of low molecular weight. Biogenic amines (BA) are natural toxins.

Drosophila tan Encodes a Novel Hydrolase Required in Pigmentation and Vision [PDF]

open access: yes, 2005
Many proteins are used repeatedly in development, but usually the function of the protein is similar in the different contexts. Here we report that the classical Drosophila melanogaster locus tan encodes a novel enzyme required for two very different ...

Evolutionary trails of plant group II Pyridoxal phosphate-dependent decarboxylase genes

open access: yesFrontiers in Plant Science, 2016
Type II pyridoxal phosphate-dependent decarboxylase (PLP_deC) enzymes play important metabolic roles during nitrogen metabolism. Recent evolutionary profiling of these genes revealed a sharp expansion of histidine decarboxylase (HDC) genes in the members

Electron transfer pathway analysis in bacterial photosynthetic reaction center [PDF]

open access: yesarXiv, 2016
A new computational scheme to analyze electron transfer (ET) pathways in large biomolecules is presented with applications to ETs in bacterial photosynthetic reaction center. It consists of a linear combination of fragment molecular orbitals and an electron tunneling current analysis, which enables an efficient first-principles analysis of ET pathways ...

Hybrid gold single crystals incorporating amino acids [PDF]

open access: yesarXiv, 2016
Composite hybrid gold crystals are of profound interest in various research areas ranging from materials science to biology. Their importance is due to their unique properties and potential implementation, for example in sensing or in bio-nanomedicine. Here we report on the formation of hybrid organic-metal composites via the incorporation of selected ...

Beyond esterase-like activity of serum albumin. Histidine-(nitro)phenol radical formation in conversion cascade of p-nitrophenyl acetate and the role of infrared light [PDF]

open access: yesarXiv, 2018
Serum albumin, recognized mainly for its capacity to act as a carrier protein for many compounds, can also actively transform some organic molecules. As a starting point in this study we consider esterase-like activity of bovine serum albumin (BSA) toward p-nitrophenyl acetate (p-NPA).

Biochemical and spectroscopic properties of Brucella microti glutamate decarboxylase, a key component of the glutamate-dependent acid resistance system [PDF]

open access: yes, 2015
In orally acquired bacteria, the ability to counteract extreme acid stress (pH < 2.5) ensures survival during transit through the animal host stomach. In several neutralophilic bacteria, the glutamate-dependent acid resistance system (GDAR) is the most ...

Nucleotide sequence alignment of hdcA from Gram-positive bacteria

open access: yesData in Brief, 2016
The decarboxylation of histidine -carried out mainly by some gram-positive bacteria- yields the toxic dietary biogenic amine histamine (Ladero et al. 2010 〈10.2174/157340110791233256〉 [1], Linares et al. 2016 〈http://dx.doi.org/10.1016/j.foodchem.2015.11.
