RT   Enterococcus faecium.";
RL   Submitted (MAR-2005) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Involved in resistance to gentamicin, tobramycin, and
CC       kanamycin. Tobramycin and kanamycin resistance is due to the ACC
CC       activity, specified by N-terminal region. The C-terminal region is a
CC       kinase that phosphorylates several 4,6-disubstituted aminoglycosides.
CC       {ECO:0000250|UniProtKB:P0A0C2}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a gentamycin + GTP = a gentamycin 2''-phosphate + GDP + H(+);

CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: In the C-terminal section; belongs to the aminoglycoside
CC       phosphotransferase family. {ECO:0000305}.
