APH
PFAM accession number:PF01636
Interpro abstract (IPR002575): This entry consists of bacterial antibiotic resistance proteins, which confer resistance to various aminoglycosides they include:- aminoglycoside 3'-phosphotransferase or kanamycin kinase / neomycin-kanamycin phosphotransferase and streptomycin 3''-kinase or streptomycin 3''-phosphotransferase. The aminoglycoside phosphotransferases inactivate aminoglycoside antibiotics via phosphorylation [(PUBMED:2167474)]. The proteins are found in a range of taxonomic groups.
