-
mutation decreases the activity at position 13 in the Pyrococcus abyssi tRNAAsp at 55°C. At 80°C the mutation has almost no negative effect on its activity towards the Pyrococcus abyssi tRNATyr(GUA)
K19I/R78A/H79N
-
mutation completely abolishes the activity at position 13 in the Pyrococcus abyssi tRNAAsp at 55°C. At 80°C the mutation nearly abolishes activity towards the Pyrococcus abyssi tRNATyr(GUA)
R78A/H79N
-
mutation decreases the activity at position 13 in the Pyrococcus abyssi tRNAAsp at 55°C. At 80°C the mutation has almost no negative effect on its activity towards the Pyrococcus abyssitRNATyr(GUA)
A78R/N79H
-
mutation has no positive effect on activity at 80°C on Pyrococcus abyssi tRNAAsp(GUA)
I27K
-
mutation increases activity at 80°C on Pyrococcus abyssi tRNAAsp(GUA) 1.6fold
N79H
-
mutation has no positive effect on activity at 80°C on Pyrococcus abyssi tRNAAsp(GUA)
additional information
generation of PUS7-knockout human stem cells, hESCs, using CRISPR/Cas9 technique. There are no differences in cell proliferation, viability, and expression of multiple pluripotency, and germ layer specific markers between wild-type and PUS7-KO cells maintained in culture over long periods of time without loss of self-renewal, but a significant increase in PUS7-KO cell size compared to controls is observed.
