Disulfide bond formation of thiols by using carbon nanotubes.

Nanoscale

Hirano A, Kameda T, Sakuraba S, Wada M, Tanaka T, Kataura H.
PMID: 28422249
Nanoscale. 2017 May 04;9(17):5389-5393. doi: 10.1039/c7nr01001j.

Clarification of the interactions between carbon nanotubes (CNTs) and proteinogenic amino acids is a key approach to understanding CNT-protein interactions. Previous studies have addressed the mechanism of the physical adsorption of amino acids onto CNTs. However, little is known...

Biochemistry and biophysics reports

Toinon A, Greco F, Moreno N, Claire Nicolai M, Guinet-Morlot F, Manin C, Ronzon F.
PMID: 29124221
Biochem Biophys Rep. 2015 Oct 26;4:329-336. doi: 10.1016/j.bbrep.2015.10.010. eCollection 2015 Dec.

Differential Scanning Calorimetry (DSC) has been used in the past to study the thermal unfolding of many different viruses. Here we present the first DSC analysis of rabies virus. We show that non-inactivated, purified rabies virus unfolds cooperatively in...

PHOTOPROTECTION OF SEA-ICE MICROALGAL COMMUNITIES FROM THE EAST ANTARCTIC PACK ICE(1).

Journal of phycology

Petrou K, Hill R, Doblin MA, McMinn A, Johnson R, Wright SW, Ralph PJ.
PMID: 27021712
J Phycol. 2011 Feb;47(1):77-86. doi: 10.1111/j.1529-8817.2010.00944.x. Epub 2011 Jan 13.

All photosynthetic organisms endeavor to balance energy supply with demand. For sea-ice diatoms, as with all marine photoautotrophs, light is the most important factor for determining growth and carbon-fixation rates. Light varies from extremely low to often relatively high...

Chemical and cellular oxidant production induced by naphthalene secondary organic aerosol (SOA): effect of redox-active metals and photochemical aging.

Scientific reports

Tuet WY, Chen Y, Fok S, Gao D, Weber RJ, Champion JA, Ng NL.
PMID: 29123138
Sci Rep. 2017 Nov 09;7(1):15157. doi: 10.1038/s41598-017-15071-8.

Exposure to air pollution is a leading global health risk. Secondary organic aerosol (SOA) constitute a large portion of ambient particulate matter (PM). In this study, the water-soluble oxidative potential (OP) determined by dithiothreitol (DTT) consumption and intracellular reactive...

High efficiency reduction capability for the formation of Fab׳ antibody fragments from F(ab).

Biochemistry and biophysics reports

Crivianu-Gaita V, Romaschin A, Thompson M.
PMID: 29124142
Biochem Biophys Rep. 2015 Apr 25;2:23-28. doi: 10.1016/j.bbrep.2015.04.004. eCollection 2015 Jul.

Antibodies have widespread applications in areas ranging from therapeutics to chromatography and protein microarrays. Certain applications require only the fragment antigen-binding (Fab) units of the protein. This study compares the cleavage efficacy of dithiothreitol (DTT), mercaptoethylamine (MEA), and dithiobutylamine...

Light-regulation of enzyme activity in anacystis nidulans (Richt.).

Planta

Duggan JX, Anderson LE.
PMID: 24435997
Planta. 1975 Jan;122(3):293-7. doi: 10.1007/BF00385278.

The effect of light on the levels of activity of six enzymes which are light-modulated in higher plants was examined in the photosynthetic procaryot Anacystis nidulans. Ribulose-5-phosphate kinase (EC 2.7.1.19) was found to be light-activated in vivo and dithiothreitol-activated...

Synthesis of a resin monomer-soluble polyrotaxane crosslinker containing cleavable end groups.

Beilstein journal of organic chemistry

Seo JH, Nakagawa S, Hirata K, Yui N.
PMID: 25550723
Beilstein J Org Chem. 2014 Nov 10;10:2623-9. doi: 10.3762/bjoc.10.274. eCollection 2014.

A resin monomer-soluble polyrotaxane (PRX) crosslinker with cleavable end groups was synthesized to develop degradable photosetting composite resins. The PRX containing 50 α-cyclodextrins (α-CDs) with disulfide end groups was initially modified with n-butylamine to obtain a resin monomer-soluble PRX....

Experimentally induced binding of phytochrome to mitochondrial and microsomal fractions in etiolated pea shoots.

Planta

Manabe K, Furuya M.
PMID: 24435120
Planta. 1975 Jan;123(3):207-15. doi: 10.1007/BF00390699.

A brief irradiation with red light of pea (Pisum sativum L.) shoot segments kept at 0° resulted in very rapid binding of both Pr and Pfr to mitochondrial and microsomal fractions. The effect was not far-red reversible. The amount...

Covalent attachment and release of small molecules from functional polyphenylene dendrimers.

Chemical communications (Cambridge, England)

Hammer BA, Baumgarten M, Müllen K.
PMID: 24413634
Chem Commun (Camb). 2014 Feb 25;50(16):2034-6. doi: 10.1039/c3cc48741e.

Herein, we report the synthesis of 2nd generation PPDs functionalized with free thiol moieties within the scaffold, which were used as anchor points for the covalent attachment of guest species (p-nitrophenol derivatives) through the oxidative formation of disulfide linkages....

The addition of dithiothreitol (DTT) to a suspension consisting of either DNA- or sodium-dodecyl-sulfate (SDS)-wrapped single-walled carbon nanotubes (SWCNTs) caused significant photoluminescence (PL) brightening from the SWCNTs, whereas PL quenching to different extents was observed for other surfactant-SWCNT suspensions....
