The selection markers were: PGK, mouse phosphoglycerate kinase promoter; NEO, neomycin phosphotransferase; HPRT, mouse hypoxanthine phosphoribosyltransferase; TK, human herpes simplex virus type 1 thymidine kinase promoter; MT, mouse metallothionein promoter; loxP, a 34 bp recombination site from phage P1.
In the third reaction, CDP-ethanolamine condenses with diacylglycerol to yield PE via the action of integral membrane enzyme 1,2-diacylglycerol ethanolamine phosphotransferase (EPT).
First, the plasmid pSilent-1 [24] was used as template to amplify the ORF and terminator of hygromycin B phosphotransferase gene hph (conferring hygromycin B resistance) with primers HygxhoI and Orfhyg.
Inhibition of glucose transport by downregulating Phosphoenolpyruvate phosphotransferase and [H.sup.+]/ATPase membrane enzymes with decreasing proton motive force is well explained, but still inhibition of enolase enzyme in glucose metabolism by bacteria to form lactic acid is most accepted mechanism of action for fluoride.
It also contains the selectable marker genes hygromycin phosphotransferase (hyg) and kanamycin (kanr).
They were obtained by using EHA-105 strain of Agrobacterium harboring pBIH binary vector that contained DREB1A controlled by an inducible promoter Lip9 and hygromycin phosphotransferase gene (hpt) as a plant selectable marker.
Negative controls for these experiments included the use of a non-relevant transcript probe (Neomycin resistance phosphotransferase gene).
This activation reflected phosphotransferase activity.
GCV resistance of HCMV is confined to mutations in the viral phosphotransferase gene (UL97) (7-9) and, less frequently, in the DNA polymerase gene (UL54) (10).
