Bunyamwera orthobunyavirus glycoprotein precursor is processed by cellular signal peptidase and signal peptide peptidase.
The M genome segment of Bunyamwera virus (BUNV)-the prototype of both the Bunyaviridae family and the Orthobunyavirus genus-encodes the glycoprotein precursor (GPC) that is proteolytically cleaved to yield two viral structural glycoproteins, Gn and Gc, and a nonstructural protein, NSm. The cleavage mechanism of orthobunyavirus GPCs and the host proteases involved have not been clarified. In thi...
متن کاملCytosolically expressed PrP GPI-signal peptide interacts with mitochondria
We previously reported that PrP GPI-anchor signal peptide (GPI-SP) is specifically degraded by the proteasome. Additionally, we showed that the point mutation P238S, responsible for a genetic form of prion diseases, while not affecting the GPI-anchoring process, results in the accumulation of PrP GPI-SP, suggesting the possibility that PrP GPI-anchor signal peptide could play a role in neurodeg...
متن کاملThe Drosophila Crumbs signal peptide is unusually long and is a substrate for signal peptide peptidase.
N-terminal signal sequences mediate nascent protein targeting to and protein insertion into the membrane of the endoplasmic reticulum. They are typically 15-30 amino acid residues long with a core hydrophobic region flanked by an N-terminal (n-) and a C-terminal region. Following cleavage by signal peptidase, some of the resulting signal peptides are further processed by signal peptide peptidas...
متن کاملCrystal structure of a bacterial signal Peptide peptidase.
Signal peptide peptidase (Spp) is the enzyme responsible for cleaving the remnant signal peptides left behind in the membrane following Sec-dependent protein secretion. Spp activity appears to be present in all cell types, eukaryotic, prokaryotic and archaeal. Here we report the first structure of a signal peptide peptidase, that of the Escherichia coli SppA (SppA(EC)). SppA(EC) forms a tetrame...
متن کاملCrystal structure of Bacillus subtilis signal peptide peptidase A.
Signal peptide peptidase A (SppA) is a membrane-bound self-compartmentalized serine protease that functions to cleave the remnant signal peptides left behind after protein secretion and cleavage by signal peptidases. SppA is found in plants, archaea and bacteria. Here, we report the first crystal structure of a Gram-positive bacterial SppA. The 2.4-Å-resolution structure of Bacillus subtilis Sp...
