[Q]: Paragraph: The SARS 3C-like proteinase (SARS-3CLpro), which is the main proteinase of the SARS coronavirus, is essential to the virus life cycle. This enzyme has been shown to be active as a dimer in which only one protomer is active. However, it remains unknown how the dimer structure maintains an active monomer conformation. It has been observed that the Ser139-Leu141 loop forms a short 3 10 -helix that disrupts the catalytic machinery in the inactive monomer structure. We have tried to disrupt this helical conformation by mutating L141 to T in the stable inactive monomer G11A/R298A/Q299A. The resulting tetra-mutant G11A/L141T/R298A/Q299A is indeed enzymatically active as a monomer. Molecular dynamics simulations revealed that the L141T mutation disrupts the 3 10 -helix and helps to stabilize the active conformation. The coil-3 10 -helix conformational transition of the Ser139-Leu141 loop serves as an enzyme activity switch. Our study therefore indicates that the dimer structure can stabilize the active conformation but is not a required structure in the evolution of the active enzyme, which can also arise through simple mutations.

[Q]: Paragraph: Seven fragments of the spike (S) gene cDNA of transmissible gastroenteritis virus (TGEV), as well as the full length cDNA, were cloned and expressed in baculovirus vectors. Piglets were immunized with cells infected with the recombinant viruses. Each of the recombinants induced TGEV-specific antibodies detected in a fixed cell enzyme immunoassay. The amino terminal half of the S protein, containing all four major antigenic sites (A, B, C and D), and encoded by a 2.2 kb fragment of the S gene, induced virus neutralizing (VN) antibody titers comparable with those induced by the complete S protein. Recombinant proteins lacking the A antigenic site, or with a deletion including the putative receptor binding sites and the D antigenic site, were not capable of inducing levels of VN antibodies similar to those induced by the whole S protein.

[Q]: Paragraph: The vascular endothelium can be considered as an organ/tissue which comprises a monolayer of endothelial cells which serve as a semipermeable cellular barrier separating the inner space of blood vessels from its surrounding tissue and to control the exchange of fluids and cells between the two compartments. Since the pulmonary circulation receives the entire cardiac output, the large surface area of the lung microvasculature is well suited for sensing mechanical, chemical, and cellular injury by inhaled or circulating substances. This endothelial barrier is dynamically regulated through exposure to these various stimuli of physiological and pathological origin and serves to regulate multiple key biological processes (including lung fluid balance and solute transport between vascular compartments). For example, an increase in vascular permeability is a necessary feature of the body's defense mechanism to provide injured tissues with access to leucocytes, resulting in tissue edema due to fluid extravasation. However, during conditions of intense lung inflammation such as observed in acute lung injury or its severer form of acute respiratory distress syndrome, the large surface area becomes a liability and provides the opportunity for profound vascular permeability resulting in massive fluid accumulation in the alveolar space and progressively leading to pulmonary failure. Alterations in vascular permeability occur not only in acute inflammatory lung disorders primarily caused by sepsis, pneumonia, and trauma which result in high rates of patient morbidity and mortality, but are an attractive target for therapeutic intervention in subacute lung inflammatory disorders such as ischemia-reperfusion injury, radiation lung injury, and asthma. Thus, understanding the mechanisms of endothelial barrier dysfunction is vital for the management and treatment of key and enigmatic pulmonary disorders.
