The hepatitis B virus (HBV) core protein (CP) forms the shell of an icosahedral nucleocapsid. In a former work, we identified 11 amino acid residues of CP exposed on the capsid surface by an alanine mutation scan as being important for capsid envelopment. We now introduced several other amino acids at six of these positions and found that almost all 27 tested point mutations at S17, K96, and I1...

N(α)-Acetyltransferases (NATs) cause the N(α)-acetylation of the majority of eukaryotic proteins during their translation, although the functions of this modification have been largely unexplored. In yeast (Saccharomyces cerevisiae), four NATs have been identified: NatA, NatB, NatC, and NatD. In this study, the N(α)-acetylation status of ribosomal protein was analyzed using NAT mutants combined...

The E2 cross section calculated by Langanke and Shoppa for the Riken experiment on the Coulomb Dissociation of B uses E2 nuclear matrix element from one sepcific model. Other nuclear models predict a consdiderably smaller E2 cross section (by approximately a factor of 3 to 4), and Langanke and Shoppa appear to assume the most optimistic scenario predicting a large E2 cross section. We also note...

A natural case of co-infection by Leishmania and Trypanosoma is reported in a dog (Canis familiaris) in south- western state of Mato Grosso do Sul, Brazil. Both amastigote and trypomastigote forms were observed after Giemsa staining of cytological preparations of the dog's bone marrow aspirate. No parasite was detected using medium culture inoculation of the sample. DNA obtained from the bone m...

The bacterium Staphylococcus can cause various health problems, particularly in hospitalized patients. Therefore, the current study aimed to isolate methicillin-resistant aureus (MRSA) strains, test their capability form a biofilm, and detect genes related virulence biofilm formation. Bacterial isolates were collected from King Faisal Specialist Hospital Children’s hospital Taif Governorate, Sa...

almonds are self incompatible, the incompatibility being controlled by a multi allelic (s-alleles) single gene. the incompatibility alleles were studied in 96 samples of wild almonds and related prunus species from 10 taxonomic groups. polymerase chain reactions were carried out with six primer sets including: three degenerate primer pairs (paconsi-f(fam)/em-pc1consrd, paconsi-f(fam)/em-pc3cons...
