this experiment was conducted to evaluate the effect of silver nanoparticles coated on clinoptilolite on performance traits, liver enzymes and blood lipid concentrations to use 375 cobb 500 broiler chickens in completely randomized design with five treatments and five replicates and 15 birds to each replicate. the use of silver nanoparticles coated on clinoptilolite improved feed conversion rat...

Glutathione S-transferase is a family of multifunctional detoxification enzymes which are mainly cytosolic that detoxify natural and exogenous toxic compounds by conjugation with glutathione. Glutathione, an endogenous tripeptide, is important as either a reducing agent or a nucleophilic scavenger. This molecule alleviates the chemical toxicity in plants by reaction of glutathione S-transferase...

The 3-hydroxypropionate cycle has been proposed to operate as the autotrophic CO2 fixation pathway in the phototrophic bacterium Chloroflexus aurantiacus. In this pathway, acetyl coenzyme A (acetyl-CoA) and two bicarbonate molecules are converted to malate. Acetyl-CoA is regenerated from malyl-CoA by L-malyl-CoA lyase. The enzyme forming malyl-CoA, succinyl-CoA:L-malate coenzyme A transferase, ...

Peptide bond formation and peptide release are catalyzed in the active site of the large subunit of the ribosome where universally conserved nucleotides surround the CCA ends of the peptidyl- and aminoacyl-tRNA substrates. Here, we describe the use of an affinity-tagging system for the purification of mutant ribosomes and analysis of four universally conserved nucleotides in the innermost layer...

Ninety six 21 day- old unsexed broiler chickens were used for the study designed to evaluate effect of different levels pawpaw leaf meal on serum biochemistry chickens. The experiment consisted four treatment groups, each in three replicates eight birds per replicate. treatments reflect inclusion meal: T1 (control 0 g/kg PLM feed), T2 (3 T3 (5 feed) and T4 (7 feed). was framed a completely rand...
