Streptococcus gordonii is a bacterial species that naturally colonizes the oral cavity of most healthy humans. It resides in the mouth as an adherent to dental surfaces and, with few exceptions, does not cause disease in individuals it inhabits. It possesses qualities that encourage its use as a vector to...
In order to produce infectious virus progeny, vaccinia virus (VV)
undergoes morphogenic proteolysis to regulate the structural rearrangements of
virus particles. Several of the major structural precursor proteins of VV are
cleaved at a conserved Ala-Gly-X (where X is any amino acid) motif by the VV
I7L core protein proteinase...
Streptococcus gordonii (S. gordonii) is being developed as a Gram-positive
expression vector for the expression of heterologous proteins. This bacterial
expression system takes advantage of the natural pathway of protein export and
anchoring on the surface of the bacterium. The expression of heterologous proteins
relies on the homologous recombination of...
L1R, a myristylated late gene product of vaccinia virus, is essential for formation of infectious intracellular mature virions (IMV). In its absence, only viral particles arrested at an immature stage are detected and no infectious progeny virus are produced. Previous studies have shown that the L1R protein is exclusively associated...
The attachment of myristic acid to the N-terminal glycine residue of many
eukaryotic and viral proteins is often essential for the acquisition of the protein's
biological activity. Vaccinia virus (VV), the prototype member of the Poxviridae,
expresses several myristylated proteins during the course of infection. Only one of
these proteins,...
Vaccinia virus (VV) encodes at least six proteins that are modified by the addition of a 14-carbon saturated fatty acid through an amide linkage and at least eight proteins that are modified post-translationally by the addition of a 16-carbon saturated fatty acid through linkage to cysteine residues. These post-translational modifications...
Vaccinia virus encodes at least eight proteins that are modified post-translationally by the addition of a 16-carbon saturated fatty acid through thioester linkage to cysteine residues. This is referred to as palmitylation of proteins. The purpose of this work was to gain an understanding of palmitylation, focusing on what defined...
Vaccinia virus (VV) is a large DNA virus belonging to the Orthopoxvirus
family. The viral replicative life cycle takes place solely within the cytoplasm
of a mammalian host cell. The VV genome contains 196 open reading frames
which are expressed in a highly regulated and temporal fashion in order to...
