ATP-dependent chaperoning activity of reticulocyte lysate.
We have developed an assay for chaperone-mediated protein renaturation using thermally denatured Firefly luciferase. Dilution of denatured luciferase (> 99% loss of activity) into reticulocyte lysate typically results in recovery of 5-15% activity. Addition of an ATP-regenerating system increases yields to > 60%, while heat shock or the addition of denatured proteins inhibits the chaperoning ac...
متن کاملA technique to increase protein yield in a rabbit reticulocyte lysate translation system.
Rabbit reticulocyte lysate (RRL) is a mammalian cell-free system for protein production. However, one of the limitations of this system is its low protein yield. Inclusion of recombinant virus proteins and specific viral structures on target mRNA could enhance protein production in RRL. Here we show that simultaneous addition of influenza A virus NS1 protein and inclusion of the encephalomyocar...
متن کاملInhibitory effect of alpha-fetoprotein on protein synthesis in a reticulocyte lysate cell-free system.
The inhibitory effect of human alpha-fetoprotein on the protein synthesis (incorporation of [3H]leucine into the total protein fraction) weas observed in a rabbit reticulocyte lysate cell-free system. The incorporation was inhibited to 50% of the control level by 14-16 microM alpha-fetoprotein, and decreased to about 15% at a concentration higher than 40 microM. An almost identical dose depende...
متن کاملFluoride inhibition of the initiation of protein synthesis in the reticulocyte lysate cell-free system.
KF (30 mM) strongly inhibits polypeptide chain initiation in the reticulocyte lysate cell-free system.. Chain elongation is partially inhibited but proceeds to a significant extent with little initiation of new chains. Polysome breakdown is incomplete after incubations as long as 20 min. Under these conditions deacylated tRNA-Met accumulates in a fraction sedimenting faster than 120 S and thus ...
متن کاملThe rabbit reticulocyte lysate as a system for studying mRNA.
In this article we describe the use of the rabbit reticulocyte lysate as an assay system for added mRNA. Some of the techniques we describe are familiar, but we have recently realised that the system can be used in rather subtile ways to provide additional information about the RNA under study. Although our own studies with viral RNA are in their early stages, we believe that the approaches we ...
