Protein Family Models

This family 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 [2]. This family also includes homoserine kinase. This family is related to fructosamine kinase Pfam:PF03881. [1]. 2163618.

Members of this family are the ycfN gene product of Escherichia coli, now identified as the salvage enzyme thiamine kinase (thiK), and additional proteobacterial homologs taken to be orthologs with equivalent function.
