Effect of long-term oral administration of extra thyroxine on oviductal expression of carbonic anhydrase and avidin-related protein-2 genes in broiler breeder hens
Avian sperm are stored in the sperm storage tubules (SSTs) of the hen oviduct for a prolonged period. The impact of avidin-related protein-2 (AVRP2) and carbonic anhydrase II (CA II) in sperm viability in the SSTs has been suggested. The aim of the present study was to investigate the effect of oral administration of a high dose of thyroxine on the oviductal expression of AVRP2<...
متن کاملpH Dependence Study of the Kinetic Reaction of Bovine Carbonic Anhydrase with 2,2'-Dithiobispyridine in the Absence and Presence of Surfactants
The pH dependence study reveals that the Cys 206 sulphydryl group of bovine carbonicanhydrase in the native form is not exposed. During the reaction of 2,2'-dithiobispyridine (2-DTP) with the enzyme, there was no absorbance change recorded. In the presence ofsurfactants, the pH dependence profiles of the apparent second order rate constants, kapp, forthe reaction of 2-DTP with bovine carbonic a...
متن کاملReport Number 568 Maximum Rate Analysis of Erythrocyte Carbonic Anhydrase in Hypercapnic Guinea Pigs
Studies have been made of the activity and concentration of erythrocyte carbonic anhydrase in guinea pigs exposed for up to seven days to atmospheres containing 15% CO2. Data are presented which indicate that adaptive processes tend to reduce the activity per mole of enzyme when the enzyme concentration is increased by such processes as hemoconcentration, i.e., during the first 24-48 hours of C...
متن کاملGas contaminants capturing by gamma-carbonic anhydrase catalyst: A quantum chemical approach
In this paper, we used quantum chemical approach to shed light on the catalytic mechanism of γ-carbonic anhydrase (γ-CA) to convert carbon dioxide to bicarbonate ion. Density functional theory (DFT) using B3LYP and UB3LYP functional and three split-valance including 6-31G*, 6-311G** and 6-311++G** basis sets were used to calculate the details of electronic structure and electronic energy of act...
