Phosphorylates the antibiotic hygromycin B. Whereas the enzyme from Streptomyces hygroscopicus (EC 2.7.1.119; hygromycin-B 7′′-O-kinase) catalyses the formation of 7′′-O-phosphohygromycin B, this enzyme, found in Escherichia coli carrying a plasmid conferring resistance to hygromycin-B, forms 4-O-phosphohygromycin B.

Harvested cells are suspended in buffer with DNase I and phenylmethylsulfonyl fluoride. The cells are lysed by sonication. Cell debris is separated by centrifugation and the soluble fraction is applied onto an Ni2+-affinity column equilibrated with buffer. The protein is eluted with a linear gradient of imidazole using a fast protein liquid-chromatography system. The eluted protein is dialyzed and applied onto a column of Q-Sepharose FF. The Hph5 protein is eluted with a linear gradient of 0-500 mM NaCl. The purified Hph5 is concentrated to 20-30 mg/ml for crystallization and stored at 20°C. Protein purification is monitored by SDS-PAGE. The selenomethionine-substituted Hph5 is purified using an Ni2+-affinity column and a Q-Sepharose FF column; this process is identical to that uses to purify the native Hph5 and is performed using buffers containing 20 mM mercaptoethanol.

Agrobacterium tumefaciens strain EHA101 containing the plasmid pIG121-Hm which harbored intron-containing beta-glucuronidase gene under the control of a 35S cauliflower mosaic virus promoter, hygromycin phosphotransferase gene, and neomycin phosphotransfease gene as reporter genes is used for transformation.

by Agrobacterium-mediated transformation. Spores of Marchantia polymorpha are germinated and grown into immature thalli. The 7-day-old immature thalli are co-cultivated with Agrobacterium and transferred directly to selective M51C agar medium after washing. Incubation of immature thalli with Agrobacterium harboring the binary plasmid pIG121Hm lead to the formation of hygromycin-resistant plantlets, whereas Agrobacterium carrying no binary plasmid did not. Hygromycin-resistant thalli with rhizoids became distinct 10 days after transfer to the selection agar medium, whereas hygromycin-sensitive plantlets developed into chlorotic cell clumps. To avoid chimerism of hygromycin-resistant thalli, isogenic lines are obtained from gemmae which arise asexually from single initial cells in cupules, and used for further analysis.
-
Co-transformation of Oryza sativa L. var. Pusa Basmati1 was done using an Agrobacterium tumefaciens strain harbouring a single-copy cointegrate vector and a multi-copy binary vector in the same cell. The T-DNA of the cointegrate plasmid pGV2260::pSSJ1 carried the hygromycin phosphotransferase and beta-glucuronidase genes. The binary vector pCam-chi11, without a plant selectable marker gene, harboured the rice chitinase gene under maize ubiquitin promoter.
