Abstract excerpt
Aminoglycoside nucleotidyltransferase 4' (ANT) is a homodimeric enzyme that modifies the C4'-OH site of aminoglycoside antibiotics by nucleotidylation. A few single- and double-residue mutants of this enzyme (T130K, D80Y, and D80Y/T130K) from Bacillus stearothermophilus show increased thermostability. This article investigates how such residue replacements, which are distant from the active site and...
