Hepatitis B virus (HBV) replication requires reverse transcription of an RNA pregenome (pgRNA) by a multifunctional polymerase (HP). HP initiates viral DNA synthesis by using itself as a protein primer and an RNA signal on pgRNA, termed epsilon (Hε), as the obligatory template. We discovered a Mn(2+)-dependent transferase activity of HP in vitro that was independent of Hε but also used HP as a ...
background: the knowledge of blood parameters is important for assessing the physiological status and health of animals. objectives: this study was conducted to determine the effect of heavy pregnancy on some serum indices of dromedary camels. methods: twenty clinically healthy female dromedary camels aged between 4-5 years were divided into two equal groups: i: pregnant camels in their last tr...
To explore the contribution of agricultural practices on enzymatic activity in Anopheles gambiae populations, collections gambiaelarve were done cotton vegetable farming (famers use for both,insecticides pest control) and subsistence (no insecticide) from district Banikoara, located Benin. Enzymatic activities such as total protein, monooxygenase P450, Glutathione-S-Transferase esterasewere inv...
UDP-glucuronosyltransferase (transferase) clones were isolated from a cDNA bank constructed in pBR322 using transferase-enriched mRNA from the livers of phenobarbital-treated rats. The enrichment of mRNA was accomplished by polysome immunoadsorption with antibody to purified mouse liver transferase. This antibody was shown to bind specifically to rat transferase by Ouchterlony double diffusion ...
Microsomal membranes from chick embryo epiphyseal cartilage were fractionated by equilibrium sucrose-density-gradient centrifugation and assayed for GlcA (glucuronic acid) transferase I (the enzyme that transfers GlcA from UDP-GlcA to Gal-Gal-Xyl of proteochondroitin linkage region), for comparison with GlcA transferase II (the GlcA transferase of chondroitin polymerization). Gal(beta1-3)Galbet...
Succinyl coenzyme A:acetoacetate coenzyme transferase (EC 2.8.3.5), an initiator of ketone body usage and absent in normal liver, has been shown to be located in mitochondria from Morris hepatoma 7288ctc using differential and density gradient centrifugation. Furthermore, tumor mitochondrial subfractionation revealed that this transferase is associated with the matrix-soluble proteins. Comparis...
We have previously characterized a cDNA that encodes a full length human UDP-GalNAc:polypeptide, N-acetylgalactosaminyltransferase (GalNAc-transferase) (J.A. Meurer et al., J. Biochem., 118, 568-574, 1995). The present report describes the characterization of the corresponding human GalNAc-transferase gene and a related pseudogene. Two human genomic libraries, lambda and P1, were screened with ...
background: hydatid cysts are formed in human body can be treated clinically by surgery or drugs such as albendazole (abz) and mebendazole (mbz). the purpose of this study was comparing the effects of abz and mbz on glutathione-s-transferase, alkaline phosphatase and protease enzymes activities in protoscoleces of hydatid cyst. methods: the culture supernatants containing the parasite excretory...
in the present study, changes of values of serum 17ß-estradiol (e2), asparate amino teransferase (ast), alanine amino transferase (alt) and lactate dehydrogenase (ldh) following intraperitoneal (i.p) injection with the aromatase inhibitor (ai) letrozole were investigated in rainbow trout (oncorhynchus mykiss). forty- eight apparently healthy rainbow trout (mean weight of 845 g) divided in four ...
