Example sentences for: ribosylation

How can you use “ribosylation” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Thus electroporation of the exoenzyme C3 fully ribosylates Rho in vivo , to the extent that no further in vitro ribosylation of Rho can be detected after cell lysis.

  • Although ribosylation of other Rho family proteins such as Rac1 can occur with C3 [ 33 ] , this seemed to be very weak [ 13 ] . In our work, C3 electroporated into the T cell line HPB-ALL caused complete ADP-ribosylation of Rho proteins (~25 kDa).

  • By this method, any further ADP ribosylation of Rho can be identified in vitro after in vivo ribosylation, thus serving as a measure of the efficiency of the electroporation procedure for introducing C3 exoenzyme into HPB-ALL cells [ 31 ] . As figure 1Bdemonstrates, electroporation of C3 transferase (Figure 1B, lane 3) prior to cell disruption prevented further ribosylation of Rho proteins in the cell lysates.

  • Although Rac1 and Cdc42 were identified in western blots of whole cell lysates prepared from the T cell lines HPB-ALL, CEM, HSB (data not shown), and PB human T lymphocytes (data not shown), there was no detection of ribosylation in the lower molecular weight Rac and Cdc42 related GTPases in HPB-ALL cells, indicating the specificity of C3.

  • After thorough washing, the cells were incubated for 1 hour at 37°C to allow in vivo ribosylation, then sonicated and lysates subjected to further C3 ribosylation by the addition of 2 μCi [ 32P]-NAD and 1 μg of C3 in ribosylation buffer.
