Osmoregulatory bicarbonate secretion exploits H(+)-sensitive haemoglobins to autoregulate intestinal O2 delivery in euryhaline teleosts.

J. Comp. Physiol. B, Biochem. Syst. Environ. Physiol. 184(7) , 865-76, (2014)

Marine teleost fish secrete bicarbonate (HCO3 (-)) into the intestine to aid osmoregulation and limit Ca(2+) uptake by carbonate precipitation. Intestinal HCO3 (-) secretion is associated with an equimolar transport of protons (H(+)) into the blood, both bein...

The enrichment of an alkaliphilic biofilm consortia capable of the anaerobic degradation of isosaccharinic acid from cellulosic materials incubated within an anthropogenic, hyperalkaline environment.

FEMS Microbiol. Ecol. 91 , fiv085, (2015)

Anthropogenic hyperalkaline sites provide an environment that is analogous to proposed cementitious geological disposal facilities (GDF) for radioactive waste. Under anoxic, alkaline conditions cellulosic wastes will hydrolyze to a range of cellulose degradat...

A role for catalase-peroxidase large loop 2 revealed by deletion mutagenesis: control of active site water and ferric enzyme reactivity.

Biochemistry 54(8) , 1648-62, (2015)

Catalase-peroxidases (KatGs), the only catalase-active members of their superfamily, all possess a 35-residue interhelical loop called large loop 2 (LL2). It is essential for catalase activity, but little is known about its contribution to KatG function. LL2 ...

GlxA is a new structural member of the radical copper oxidase family and is required for glycan deposition at hyphal tips and morphogenesis of Streptomyces lividans.

Biochem. J. 469 , 433-44, (2015)

Streptomyces lividans displays a distinct dependence on copper to fully initiate morphological development. Evidence has accumulated to implicate the participation of an extracytoplasmic cuproenzyme in morphogenesis. In the present study, we show that GlxA fu...

C-phycocyanin prevents cisplatin-induced mitochondrial dysfunction and oxidative stress.

Mol. Cell Biochem. 406 , 183-97, (2015)

The potential of C-phycocyanin (C-PC) to prevent cisplatin (CP)-induced kidney mitochondrial dysfunction was determined in CD-1 male mice. The CP-induced mitochondrial dysfunction was characterized by ultrastructural abnormalities and by decrease in the follo...

Effects of age increase on hepatic expression and activity of cytochrome P450 in male C57BL/6 mice.

Arch. Pharm. Res. 38 , 857-64, (2015)

Effects of aging on hepatic expression and activity of cytochrome P450 (CYP) isoforms were investigated in male mice aged 2, 6, 18, and 30 months. Microsomal protein, total CYP, cytochrome b5 and NADPH-dependent cytochrome P450 reductase contents in liver wer...

Deletion of nfnAB in Thermoanaerobacterium saccharolyticum and Its Effect on Metabolism.

J. Bacteriol. 197 , 2920-9, (2015)

NfnAB catalyzes the reversible transfer of electrons from reduced ferredoxin and NADH to 2 NADP(+). The NfnAB complex has been hypothesized to be the main enzyme for ferredoxin oxidization in strains of Thermoanaerobacterium saccharolyticum engineered for inc...

Baicalin inhibits the fenton reaction by enhancing electron transfer from Fe (2+) to dissolved oxygen.

Am. J. Chin. Med. 43(1) , 87-101, (2015)

Sho-saiko-to is an herbal medicine that is known to have diverse pharmacological activities and has been used for the treatment of various infectious diseases. Here, we examined the effects of baicalin, a compound isolated from Sho-saiko-to, and the effects o...

The use of dithionite reduction to identify the essential tyrosine residue in the F1-ATPase from the thermophilic bacterium, PS3, that reacts with 7-chloro-4-nitrobenzofurazan.

Arch. Biochem. Biophys. 245 , 8, (1986)

When the F1-ATPase from the thermophilic bacterium, PS3, was inactivated by greater than 90% with 7-chloro-4-nitro[14C]benzofurazan ([14C]Nbf-Cl) at pH 7.4, 1.4 mol of [14C]Nbf were incorporated per mol of enzyme. After pepsin digestion of the labeled enzyme ...

Mutations designed to modify the environment of the primary electron donor of the reaction center from Rhodobacter sphaeroides: phenylalanine to leucine at L167 and histidine to phenylalanine at L168.

Biochemistry 32 , 3498, (1993)

Two mutations, L168 His to Phe and L167 Phe to Leu, were made in residues near the primary electron donor, a bacteriochlorophyll dimer, of the reaction center from Rhodobacter sphaeroides. Blue shifts of 10-15 nm in the 865-nm band of the donor were observed ...
