Formate Dehydrogenases Reduce CO 2 Rather than HCO 3 − : An Electrochemical Demonstration

Rates of unfolding, rather than refolding, determine thermal stabilities of thermophilic, mesophilic, and psychrotrophic 3-isopropylmalate dehydrogenases.

The relationship between the thermal stability of proteins and rates of unfolding and refolding is still an open issue. The data are very scarce, especially for proteins with complex structure. Here, time-dependent denaturation-renaturation experiments on Thermus thermophilus, Escherichia coli, and Vibrio sp. I5 3-isopropylmalate dehydrogenases (IPMDHs) of different heat stabilities are present...

CO 2 gradients and acidification by transport of HCO 3 in turtle bladders.

SCHILB, THEODORE P., AND WILLIAM A. BRODSKY. CO, gradients and acidicfication by transport of HCO, in turtle bladders. Am. J. ‘Physiol. 222(Z) : 272-281. 1972.-During acidification of the mucosal fluid in turtle bladder sacs, the final mucosal [COJ and transmural gradient of [CO,] are dependent on: the serosal [CO,], the transport rate and clearance of bicarbonate, the buffer “poise” of the muc...

Simultaneous Transport of CO(2) and HCO(3) by the Cyanobacterium Synechococcus UTEX 625.

A mass spectrometer was used to simultaneously follow the time course of photosynthetic O(2) evolution and CO(2) depletion of the medium by cells of the cyanobacterium Synechococcus leopoliensis UTEX 625. Analysis of the data indicated that both CO(2) and HCO(3) (-) were simultaneously and continuously transported by the cells as a source of substrate for photosynthesis. Initiation of HCO(3) (-...

Co-infection of Ticks: The Rule Rather Than the Exception.

INTRODUCTION Ticks are the most common arthropod vectors of both human and animal diseases in Europe, and the Ixodes ricinus tick species is able to transmit a large number of bacteria, viruses and parasites. Ticks may also be co-infected with several pathogens, with a subsequent high likelihood of co-transmission to humans or animals. However few data exist regarding co-infection prevalences, ...
