Beside its hydrolytic action, the low Mr PTPases demonstrate phosphotransferase

Large-scale purification and acute toxicity of hygromycin B phosphotransferase
The bactericidal actions of parabens can thus be interpreted as being due to irreversible damage to key enzymes, such as those of the phosphotransferase
system (Ma and Marquis 1996).
6) Both xylitol and fructose are brought into the cell by a fructose phosphotransferase
type II (nptII), originally isolated from the TnS transposon of Escherichia coli encodes a phosphotransferase
For selection purposes pSRNG expresses neomycin phosphotransferase
and green fluorescent protein (GFP) from a single IRES-containing transcript controlled by the phosphoglycerokinase (PGK) promoter (13).
The molecular test accurately detects key genetic mutations by sequencing the CMV UL97 phosphotransferase
gene and the CMV UL54 DNA polymerase gene.
Resistance is due to the production of the aminoglycoside-modifying enzyme acetyltransferase (encoded by the aac gene) and phosphotransferase
(encoded by the aph gene), which modify the drugs by acetylation or phosphorylation.
High-level gentamicin resistance is associated with a bifunctional enzyme possesing acetylase (6') and phosphotransferase
(2') activities (Table I) (33), conferring resistance to all aminoglycosides except streptomycin.
Purification and characterization of microbially expressed neomycin phosphotransferase
II (NPTII) protein and its equivalence to the plant expressed protein.
