Recombinant Klebsiella pneumoniae Kanamycin kinase type II/NEO

Source: E.coli. MW :29kD. Recombinant Klebsiella pneumoniae Aminoglycoside 3'-phosphotransferase is produced by our E.coli expression system and the target gene encoding Met1-Phe264 is expressed. Aminoglycoside 3'-phosphotransferase (APH (3') ), also known as aminoglycoside kinase, is an aminoglycoside-modifying enzyme and widely presented in resistant bacteria. These ATP-dependent enzymes phosphorylate the 3'-hydroxyl of a variety of aminoglycosides including kanamycins, neomycins, paromomycins, neamine, ribostamycin, geneticin, and paromamine. These phosphorylated aminoglycosides fail to bind to their respective ribosomal binding sites with high affinity; hence resistance is conferred to the drugs that are phosphorylated. APH (3') is primarily found in certain species of gram-positive bacteria.
