I27K
mutation increases activity at 80°C on Pyrococcus abyssi tRNAAsp(GUA) 1.6fold
694463
5.4.99.27
K19I
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)
694463
5.4.99.27
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)
