COMMENTARY

LITERATURE

D394A

Streptomyces coelicolor

Q9L1K2

the maltosyl transferase activity of the mutant is more than 4 orders of magnitude lower than that of the wild type protein

737691

E423A

Streptomyces coelicolor

Q9L1K2

the mutant turns over alpha-maltose 1-phosphate about 500times slower than the wild type enzyme
