AIDS Res Ther. 2015 Mar 19;12:7. doi: 10.1186/s12981-015-0048-9. eCollection 2015.

BACKGROUND: Antimalarials quinacrine (Qc) and chloroquine (Cq) intercalate DNA, potentiate the activity of other drugs and have lysosomotropic, anti-inflammatory and antiviral activities that could increase the effect of the 3'-azido-3'-deoxythymidine (AZT) antiretroviral agent. The aim of the current study...

The search for small molecule inhibitors of Ebola virus (EBOV) has led to several high throughput screens over the past 3 years. These have identified a range of FDA-approved active pharmaceutical ingredients (APIs) with anti-EBOV activity in vitro and...

The Chlorophyll Biosynthetic Enzyme Mg-Protoporphyrin IX Monomethyl Ester (Oxidative) Cyclase (Characterization and Partial Purification from Chlamydomonas reinhardtii and Synechocystis sp. PCC 6803).

Plant physiology

PMID: 12226378
Plant Physiol. 1996 Sep;112(1):105-114. doi: 10.1104/pp.112.1.105.

A universal structural feature of chlorophyll molecules is the isocyclic ring. This ring is formed by the action of the enzyme Mg-protoporphyrin IX monomethyl ester (oxidative) cyclase, which catalyzes a complex reaction in which Mg-protoporphyrin IX monomethyl ester is...

Solubilization and Separation of a Plant Plasma Membrane NADPH-O2- Synthase from Other NAD(P)H Oxidoreductases.

Plant physiology

Van Gestelen P, Asard H, Caubergs RJ.
PMID: 12223822
Plant Physiol. 1997 Oct;115(2):543-550. doi: 10.1104/pp.115.2.543.

Solubilization and ion-exchange chromatography of plasma membrane proteins obtained from bean (Phaseolus vulgaris L.) seedlings resulted in a single NAD(P)H-O2--synthase protein peak. This enzyme showed a high preference toward NADPH as a substrate (reaction rate, 27.4 nmol O2- produced...

Evidence for a highly specific k/h antiporter in membrane vesicles from oil-seed rape hypocotyls.

Plant physiology

PMID: 16668511
Plant Physiol. 1991 Nov;97(3):1212-20. doi: 10.1104/pp.97.3.1212.

We present evidence strongly suggesting that a proton gradient (acid inside) is used to drive an electroneutral, substrate-specific, K(+)/H(+) antiport in both tonoplast and plasma membrane-enriched vesicles obtained from oilseed rape (Brassica napus) hypocotyls. Proton fluxes into and out...

Effect of Ca and Calmodulin on DeltapH Formation in Tonoplast Vesicles from Corn Roots.

Plant Physiol. 1990 Mar;92(3):850-4. doi: 10.1104/pp.92.3.850.

The effects of calmodulin (CaM) on ATPase activity and ATP-dependent formation of a proton gradient (DeltapH) were studied in tonoplast membrane vesicles from corn (Zea mays L.) roots. At 0.6 micromolar, CaM stimulated ATPase activity by about 20% in...

Localization of a proton-translocating ATPase on sucrose gradients.

Plant physiology

PMID: 16662623
Plant Physiol. 1982 Oct;70(4):1115-9. doi: 10.1104/pp.70.4.1115.

Ionophore-stimulated ATPase activity and ATP-dependent quinacrine quench were enriched in parallel when microsomal vesicles were prepared from corn (Crow Single Cross Hybrid WF9-Mo17) roots and collected on a cushion of 10% dextran. Activities were highest in the apical 1.5...

Anion-sensitive, h-pumping ATPase in membrane vesicles from oat roots.

Plant physiology

PMID: 16662875
Plant Physiol. 1983 Mar;71(3):610-7. doi: 10.1104/pp.71.3.610.

H(+)-pumping ATPases were detected in microsomal vesicles of oat (Avena sativa L. var Lang) roots using [(14)C]methylamine distribution or quinacrine fluorescent quenching. Methylamine (MeA) accumulation into vesicles and quinacrine quench were specifically dependent on Mg,ATP. Both activities reflected formation...

Separation of two types of electrogenic h-pumping ATPases from oat roots.

Plant physiology

PMID: 16663344
Plant Physiol. 1983 Dec;73(4):921-8. doi: 10.1104/pp.73.4.921.

Microsomal vesicles of oat roots (Avena sativa var Lang) were separated with a linear dextran (0.5-10%, w/w) or sucrose (25-45%, w/w) gradient to determine the types and membrane identity of proton-pumping ATPases associated with plant membranes. ATPase activity stimulated...

Characterization of in vitro proton pumping by microsomal vesicles isolated from corn coleoptiles.

Corn (Zea mays L. cv Golden Cross Bantam) coleoptile microsomal vesicles have been isolated which are capable of ATP-driven H(+)-transport as measured by [(14)C]methylamine accumulation and quinacrine fluorescence quenching. Formation of the pH gradient in vitro shows a high...

Studies on H-Translocating ATPases in Plants of Varying Resistance to Salinity : I. Salinity during Growth Modulates the Proton Pump in the Halophyte Atriplex nummularia.
