Crystalline arrays of proteinaceous subunits forming surface layers (S-layers) are now recognized as one of the most common outermost cell envelope components of prokaryotic organisms. The surface layer protein of Lactobacillus acidophilus ATCC4356 is composed of a single species of protein of apparent molecular weight of 43-46 KDa. Considering the Lactobacillus acidophilus ATCC4356 having the ...
Abstract Backgraound: Entamoeba histolytica antigenic markers such as Serine-Rich E. histolytica protein (SREHP) have recently been used for vaccine preparation, genetic diversity studies of Entamoeba histolytica isolates and for differentiation between E. histolytica and E. dispar species. This study was carried out with the aim of expression of a recombinant Serine Rich E. histolytica prot...
Many viruses encode scaffolding and coat proteins that co-assemble to form procapsids, which are transient precursor structures leading to progeny virions. In bacteriophage P22, the association of scaffolding and coat proteins is mediated mainly by ionic interactions. The coat protein-binding domain of scaffolding protein is a helix turn helix structure near the C terminus with a high number of...
The R17/MS2 coat protein serves as a translational repressor of replicase by binding to a 19 nt RNA hairpin containing the Shine-Dalgarno sequence and the initiation codon of the replicase gene. We have explored the structural features of the RNA operator site that are necessary for efficient translational repression by the R17/MS2 coat protein in vivo . The R17/MS2 coat protein efficiently dir...
Background and Objective: Use of elastin-like proteins (ELPs) provides high-performance protein purification without need for chromatography. In line with cost reduction and facilitation of recombinant proteins purification, which represent a high percentage of production costs, in this project, we eliminated the need for proteases in the process of separation of recombinant proteins from ELP b...
Assembly of certain classes of bacterial and animal viruses requires the transient presence of molecules known as scaffolding proteins, which are essential for the assembly of the precursor procapsid. To assemble a procapsid of the proper size, each viral coat subunit must adopt the correct quasiequivalent conformation from several possible choices, depending upon the T number of the capsid. In...
From in vitro protein synthesis studies and nucleotide sequence analysis it has been deduced that, unlike the major coat proteins of the hitherto studied filamentous bacterial viruses Ff (M13, fd and f1), IKe and Pf1, the major coat protein of the filamentous Pseudomonas aeruginosa virus Pf3 is not synthesized as a precursor containing a leader signal polypeptide at its N-terminal end. From the...
Outbreaks of the Southern rice black-streaked dwarf virus (SRBSDV) have caused significant losses in many rice-growing areas Vietnam, especially both North and Central Vietnam recent years. To detect virus, traditional reverse transcription polymerase chain reaction (RT-PCR) methodology immunoassays are currently employed. RT-PCR is accurate but requires expensive chemicals instruments, as well...
Rice stripe virus (RSV) is a plant virus, and its infection leads to devastating disease that often causes serious yield losses in rice-producing regions. In this study, the capsid protein (CP) gene of RSV was cloned expressed E. coli (Rosetta), purified recombinant His-CP used immunize New Zealand white rabbits . After six weeks, polyclonal antibody against (PAb-CP ) obtained from serum immuni...
Endospore formation by Bacillus subtilis is a complex and dynamic process. One of the major challenges of sporulation is the assembly of a protective, multilayered, proteinaceous spore coat, composed of at least 70 different proteins. Spore coat formation can be divided into two distinct stages. The first is the recruitment of proteins to the spore surface, dependent on the morphogenetic protei...
