LITERATURE
C294S
the wild-type and the C294S mutant strains are stable after heating for 10 min at 60°C
E150R
less thermostable than wild-type enzyme, stable for 10 min at 50°C, showing a significant loss of activity at 60°C. kcat/Km for 5'-deoxyadenosine is 93fold lower than the kcat/Km for the wild-type enzyme
Y136R
less thermostable than wild-type enzyme, stable for 10 min at 50°C, showing a significant loss of activity at 60°C. kcat/Km for 5'-deoxyadenosine is 535fold lower than the kcat/Km for the wild-type enzyme
Y136R/E150R
less thermostable than wild-type enzyme. kcat/Km for 5'-deoxyadenosine is 290000fold lower than the kcat/Km for the wild-type enzyme
