Functional proteomic analysis of Ankaferd® Blood Stopper

open access: yesTurkish Journal of Hematology, 2010
OBJECTIVE: Ankaferd® Blood Stopper (ABS) comprises a standardized mixture of the plants Thymus vulgaris, Glycyrrhiza glabra, Vitis vinifera, Alpinia officinarum, and Urtica dioica. The basic mechanism of action for ABS is the formation of an encapsulated

NADP+-Malic Enzyme and Organic Acid Levels in Developing Tomato Fruits [PDF]

open access: yesJournal of the American Society for Horticultural Science, 1992
Tomato (Lycopersicon esculentum Mill., cv. Ohio 7814) fruits were harvested weekly following flowering to relate changes in NADP + -malic enzyme (NADP-ME) activity and major organic acids (malate and citrate) to fruit development.

DNA‐Enzyme Hybrid Nanostructures: Functional Materials to Modulate Enzymatic Activity

open access: yesSmall, EarlyView.
DNA–enzyme hybrid nanostructures enable precise spatial and stoichiometric control over enzyme organization, offering a powerful platform to modulate catalytic activity. This review critically evaluates key mechanistic hypotheses, including proximity effects, microenvironment changes, confinement, and stabilization, as well as highlighting ...

Pyruvate uptake induced by a pH jump in mesophyll chloroplasts of maize and sorghum, NADP-malic enzyme type C4 species

open access: yes, 1990
A sudden pH decrease (pH jump) of the medium enhanced pyruvate uptake in the dark in mesophyll chloroplasts (MCp) of Zea mays and Sorghum bicolor, NADP-malic enzyme type C4 plants, while it was reported that a Na+ jump enhanced pyruvate uptake in MCp of ...

Phylogeny of C4-photosynthesis enzymes based on algal transcriptomic and genomic data supports an archaeal/proteobacterial origin and multiple duplication for most C4-related genes.

open access: yesPLoS ONE, 2014
Both Calvin-Benson-Bassham (C3) and Hatch-Slack (C4) cycles are most important autotrophic CO2 fixation pathways on today's Earth. C3 cycle is believed to be originated from cyanobacterial endosymbiosis.

Maternal Lead Exposure Induces Glandular Alterations in the Salivary Glands of Rat Male Offspring

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Lead (Pb) is a widely distributed environmental pollutant that is highly noxious due to its toxicokinetic characteristics. Pb exposure can damage vital organ systems, including the central nervous and stomatognathic systems. As salivary glands play an important role in oral homeostasis, this study aimed to investigate the effects of maternal ...

Structural basis of regioselective double halogenation of the β‐carboline tryptoline by the single‐component halogenase AetF

open access: yesActa Crystallographica Section D, EarlyView.
A structure of the flavin‐dependent single‐component tryptophan halogenase AetF bound to the non‐native tricyclic substrate tryptoline reveals a binding pose analogous to l‐tryptophan that directs C6‐first halogenation. Product analysis identifies 6,8‐dibromotryptoline as the final product.Flavin‐dependent halogenases (FDHs) offer a biocatalytic route ...

Isolation of mutants of Escherichia coli lacking NAD- and NADP-linked malic enzyme activities [PDF]

open access: yes, 1975
SummaryWhen Escherichia coli utilizes C4-dicarboxylic acids as sole sources of carbon and energy for growth, phosphoenolpyruvate is synthesized by means of phosphoenolpyruvate carboxykinase or by sequential action of malic enzyme and phosphoenolpyruvate ...

Quaternary structure of pigeon liver malic enzyme

open access: yes, 1990
Pigeon liver malic enzyme (EC 1.1.1.40) has a double dimer quaternary structure. The NADP+ analogs, aminopyridine adenine dinucleotide phosphate and nicotinamide-1.N6-ethenoadenosine dinucleotide phosphate, bind to the enzyme anti-cooperatively.

In vitro and in vivo metabolism profiles of cathinone and pseudoephedrine: Discrimination between khat and pseudoephedrine uses

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract In the present study, the metabolism of khat (Catha edulis) and pseudoephedrine was compared with the aim of identifying objective criteria that could be used to discriminate between them for forensic and doping‐control purposes. An in vitro study using human liver microsomes and an in vivo study using rat urine were performed under harmonized
