Function
This enzyme is the most clinically important aminoglycoside-modifying enzyme in Gram-positive bacteria, responsible for high-level resistance in both Enterococci and Staphylococci. And this bacterial enzyme phosphorylates many 4,6-disubstituted aminoglycoside antibiotics that have a hydroxyl group at position 2'', including kanamycin A, kanamycin B, tobramycin, dibekacin, arbekacin, amikacin, gentamicin C, sisomicin and netilmicin.
