Words similar to tyr
Example sentences for: tyr
How can you use “tyr” in a sentence? Here are some example sentences to help you improve your vocabulary:
The p51 subunit is generated via endoproteolytic cleavage of the p66 subunit between Phe 440 and Tyr 441 [ 5 6 ] . The larger subunit (p66) contains both polymerase and RNase H activities, while the smaller subunit (p51) lacks these functions, in context of the heterodimer [ 7 8 ] . However, both the p66 and p51 monomers are functionally inactive when dissociated from each other [ 9 ] . Several years have passed since it was first suggested that agents that could specifically disrupt the dimerization of HIV-1 RT might prove a worthwhile antiretroviral strategy [ 10 ] , though such agents have yet to be developed.
Strikingly, the nematode protein has greatest similarity (56% amino-acid identity) to GSI from the rhizobial bacterium, Mesorhizobium loti , including conservation of Tyr397.
This catenation activity observed with topoisomerase I and Top67 was unlikely to be due to contaminating topoisomerase III activity since it was not observed with the ZD domain purified under almost identical procedures and a site-directed mutant with substitution of the active site Tyr319 by phenylalanine also did not exhibit this activity (Figure 6a).
It has been established that, to achieve its maximal transcriptional activity, STAT1 must be phosphorylated on both Tyr701 and Ser727 [ 32 ] . Phosphorylation of STAT1 on Ser727 occurs in response to LPS, UV irradiation and other agents that activate the p38MAPK pathway [ 33 ] . As phorbol esters can also stimulate the MAPK cascade through activation of PKC [ 34 ] , it is tempting to speculate that combined treatment of cells with PMA and IFNg could increase the pool of STAT1 molecules phosphorylated on both Tyr701 and Ser727.
The expected S is one because only one mutation (ttc) is silent, and the expected R is also one because only one point mutation of ttt (tat) codes for Tyr, so the expected R:S is one, in this case.
